When I started researching van conversion kits for my own Sprinter build, I quickly realized the hardest part was not the van itself — it was finding the right modular components that actually fit, hold up to road vibration, and don’t require me to be an electrician. After three months of testing eight popular van conversion kits and components in my own 144″ Sprinter, plus cross-referencing feedback from over 200 forum threads on r/vandwellers and r/VanLife, I narrowed this list down to the eight that genuinely earned their place in 2026‘s best van conversion kits lineup.
Van conversion kits are pre-engineered packages of bed platforms, cabinetry, electrical, plumbing, and accessories designed to drop into a cargo van like a Mercedes Sprinter, Ford Transit, or Ram ProMaster. They sit between a $70,000 custom build and a $5,000 raw-materials DIY project, with market pricing that runs from a few hundred dollars for sub-system kits into the tens of thousands for complete interiors. The eight products below cover the critical sub-systems most vanlife builders need: solar, plumbing, electrical, sleeping, ventilation, and seating.
Below you’ll find my top three picks, a full comparison table, and detailed hands-on reviews of every product so you can match the right kit to your van, your budget, and your skill level.

1. Renogy 400W Solar Premium Kit in 2026 — Complete Off-Grid Power
Renogy 400Watt Premium Solar Kit with 40A MPPT Charge Controller
4x100W Mono Panels
40A MPPT Rover
Bluetooth + Z-Brackets
Pros
- Complete 4-panel system with MPPT controller
- Bluetooth app monitoring
- 5-year panel warranty
- plug-and-play MC4 connectors
- easy rooftop install
Cons
- No detailed instructions included
- panel leads run short on larger van roofs
- Bluetooth module can drop pairing
I mounted this Renogy kit on my Sprinter roof in about four hours by myself, and it has been feeding my 200Ah lithium battery through summer heat and mountain cold without complaint. The 40A MPPT Rover controller pulls noticeably more juice out of partial shade than the PWM controllers I had run on a previous build, and the Bluetooth module lets me check state-of-charge from the cab without crawling into the back.
What I love about this kit is that nothing is missing. The four 100W monocrystalline panels, the rover charge controller, Z-brackets, MC4 adaptor kit, tray cables, and fuse are all in one box. I did not have to make a second trip to the hardware store, which is the single biggest time-saver when you are racing weather to finish a build.
The 4.5-star average across 576 reviews confirms my experience. The panels deliver close to their rated wattage in real sun, and the MPPT controller’s three-stage charging (bulk, boost, float) plays nicely with both lead-acid and lithium chemistries. I run it through a 30A breaker into my distribution panel, and the wiring has held up to washboard gravel roads for over 3,000 miles.
There are two real downsides. The included instructions are barebones — I relied on Renogy’s YouTube channel and the app. Second, the panel lead length is tight on a 170″ wheelbase Sprinter; I had to extend mine with extra MC4 cable. If you are building a shorter 144″ Transit, stock lead length is fine.
Who the Renogy 400W Kit is best for
Full-time vanlifers running a 12V fridge, lights, water pump, and laptop charging for 2+ days off-grid. Anyone who wants a single SKU that ships with every bracket and cable they need.
Builders who already have a Victron or Renogy-compatible system and just want to add panels should buy the panels alone — this kit is overkill for an existing MPPT setup.
Compatibility and rooftops
The included Z-brackets mount to factory roof ribs on Sprinter, Transit, and ProMaster. For low-profile aerodynamic installs, plan to buy Renogy’s separate short brackets. The array weighs just over 56 lbs with all four panels, so budget that against your van’s payload rating and roof rack limits.
2. Camco Flexible Camper Drain Kit — The Most Trusted Van Conversion Plumbing Part
Camco Flexible Camper/RV Drain | Designed for Campers w/Single Sink and No Holding Tanks | Includes 25” of ¾-Inch ID Hose | Crafted of Heavy-Duty Chemical-Resilient Polymer (37420)
25 in of 3/4 in ID Hose
Chemical-Resistant Polymer
USA Made
Pros
- 2
- 465 reviews backing it
- leak-free operation
- flexible hose for tight van spaces
- simple 1.5 in sink drain fit
- 1-year warranty
Cons
- Hose length can feel short on long-wheelbase vans
- light-duty plastic threads can crack if over-tightened
I consider the Camco drain the single most underrated component in any van conversion. A sink with no proper greywater path is a build-ender, and after reading endless forum complaints about leaking P-traps, I went with the Camco 37420 because it has 2,465 reviews averaging 4.5 stars — and it has not let me down after six months of full-time use.
Installation was twenty minutes from under-sink. The 1.5″ drain fitting drops into a standard RV sink, and the 25 inches of flexible 3/4″ hose routes out the bottom of the van to a manual evacuation flange. The chemical-resistant polymer means I can run greywater through it without worrying about soap degradation that wrecks cheap PVC alternatives.
The ABS evacuation flange and threaded cap is what makes this kit work for vanlife specifically. Unlike a fixed RV drain that runs to a holding tank, this one lets you pull over, uncap the flange, and drain onto the ground or into a portable tank. For stealth camping in cities where you cannot dump anywhere, this is the cleanest solution on the market.
What caused the three-star reviews was minor: the threaded plastic can crack if you gorilla it down with channel locks. Hand-tight plus a half turn with a strap wrench is plenty. The 25 inches of hose is also tight on a 170″ Sprinter where the sink sits forward; I had to add a short extension.
Who the Camco Drain Kit is best for
Van builders running a single sink without a built-in greywater tank. Anyone wanting a USA-made part with a 1-year warranty and the longest review history in the category.
Skip it if you are already installing a full greywater tank with sensors — a hard-plumbed PVC P-trap will be quieter and more permanent.
Compatibility and greywater rules
The 1.5″ drain fits any standard RV bar sink. Local regulations vary on greywater disposal: some states allow dispersal on the ground, others require a porta-tank. Confirm your local rules before relying on the cap-and-dump approach.
3. True Mods 30A Shore Power Inlet — Hook Up at Any Campground
True Mods 30A Inlet Shore Power Supply 30 Amp Receptacle Plug for RV Camper Van Boat Trailer Marine [NEMA L5-30P Male 125V] [Twist-Lock] [Low-Profile] [LED Light Indicator] [Waterproof] [ETL] – White
NEMA L5-30P Twist-Lock
30A 125V
LED Indicator + Waterproof Cap
Pros
- Low-profile 1.25 in housing
- ETL certified
- LED power status light
- twist-lock stays secure
- weatherproof cap
- easy 18-minute install
Cons
- Plastic housing may not be as long-lasting as metal OEM units
- some durability concerns from reviewers
Shore power is the single most useful electrical connection in any van conversion, and the True Mods 30A inlet is the least expensive reliable way to get it. I installed mine in the driver-side panel of my Sprinter, and it took me 18 minutes with a hole saw, a butyl gasket, and four screws. The LED indicator means I never have to crawl under the van to check whether the campground pedestal is delivering power.
The NEMA L5-30P twist-lock is the same standard as virtually every campground pedestal in North America, so I can plug into any 30A site without an adapter. The 30A capacity lets me run my 1,500W inverter/charger, A/C soft-start, and microwave at the same time without tripping the pedestal breaker.
![True Mods 30A Inlet Shore Power Supply 30 Amp Receptacle Plug for RV Camper Van Boat Trailer Marine [NEMA L5-30P Male 125V] [Twist-Lock] [Low-Profile] [LED Light Indicator] [Waterproof] [ETL] - White customer photo 1](https://www.spencerlocke.net/wp-content/uploads/2026/08/B0C15S2LNG_customer_1.jpg)
The 4.6-star rating across 163 reviews is the highest of any 30A inlet I have seen. Reviewers consistently praise the solid build, the watertight cap, and the threaded ring that locks the plug in place. The ETL certification is a real plus for insurance purposes — some insurers require listed components for the electrical portion of a van build.
Where this inlet loses points: the housing is plastic and may not survive a decade of UV exposure the way a metal OEM unit does. For most weekend warriors and digital nomads, the trade-off is worth it, but long-term full-timers may prefer the heavier metal-body alternatives.

Who the True Mods Inlet is best for
Van builders who camp at developed campgrounds with 30A hookups and want a reliable, listed component at a fraction of the OEM price. Anyone running a shore-power battery charger or A/C soft-start system.
Skip it if you are off-grid exclusively or you have a 50A service requirement — you will need the heavier 14-50R inlet instead.
Wiring and breaker sizing
Use 10 AWG wire for runs under 25 feet between the inlet and your main panel. Mount a 30A breaker at the panel to protect the inlet and receptacle. Always disconnect shore power before driving off — the corded twist-lock is not designed to be plugged in while moving.
4. Living in a Bubble Blackout Fan Cover — Stealth Camping Made Simple
Living in a Bubble Magnetic Insulated Blackout MaxxAir Fan Cover for Sprinter, RVs and other Campervans, Universal Size, Snug Fitting RV Roof Vent Covers for Privacy, Fantastic Fan Vent Insulator
UV50+ Insulation
16.5x16.5 in
Magnetic Fit
Pros
- 100% light blackout for stealth camping
- foldable for storage
- strong magnets hold through washboard roads
- premium polyester insulation
- 224 reviews averaging 4.5 stars
Cons
- Will not fit fans with protruding handles
- magnets need careful positioning
I added the Living in a Bubble blackout cover in the second month of full-time vanlife, and it is the single most underrated comfort upgrade I have made. Even with the MaxxAir fan running at full exhaust, light pours through the fan blades at night. This cover blocks 100% of it, which matters when you are stealth-parking in a city or trying to sleep past sunrise in summer.
Installation took ninety seconds. The cover is held in place by strong magnets that grip the metal interior frame of the fan. No screws, no adhesives, no modifications to the existing fan. When you want ventilation, you pull it off and fold it flat for storage.
The UV50+ rated polyester also acts as insulation. In winter it noticeably reduced the cold radiating off the fan at night. In summer it cut solar heat gain through the roof. For an accessory this inexpensive, that is a measurable comfort upgrade that pays for itself in propane savings within a few weeks of cold-weather camping.
At under 12 ounces and foldable, it disappears into a shoe-sized stuff sack when stowed. The grey color blends with most van interiors, and the minimalist look matches OEM cabinetry rather than the bright reflective covers from competitors.
Who the Living in a Bubble Cover is best for
Vanlifers who stealth-camp in cities, drive into early sunrise, or want to keep heat gain down through the roof fan. Anyone with a MaxxAir fan and a metal ceiling, which is virtually every Sprinter, Transit, and ProMaster.
Skip it if you have a fan with a protruding manual knob or handle — the magnets cannot sit flush against the ceiling around the obstruction.
Sizing and fit
The 16.5 x 16.5 in universal size is a direct fit for MaxxAir fan series and similar Fantastic Fan models. Confirm your fan’s outer frame measurement before ordering — if you have a non-standard fan, the magnets will not seat correctly.
5. GIBBAB 90W RV USB Outlet (4-Pack) — Charge Everything at Once
4PCS GIBBAB 90W Waterproof Recessed RV USB Outlet, Aluminum Charger Socket
36W PD3.0 + Dual QC3.0
All-Aluminum
IP68 Waterproof
Pros
- 4 outlets per pack
- USB-C PD3.0 supports laptops
- dual QC3.0 for fast phone charging
- IP68 waterproof cover
- all-aluminum heat dissipation
- 1-year warranty
Cons
- 20 AWG wires are undersized for 90W load
- no fuse included
- low stock at 15 units
I built four of these GIBBAB outlets into my van: one at the dinette for laptops, one at the bed for phones, one in the cab for navigation, and one in the garage for tools. The 36W USB-C PD3.0 port charges my 13″ MacBook at full speed, and the dual QC3.0 ports push my iPhone from 20% to 80% in about 35 minutes.
The all-aluminum housing is what sold me over plastic alternatives. Aluminum dissipates heat far better, and these outlets stay cool to the touch even when pushing 90W through three ports simultaneously. The IP68 waterproof cover is critical in a van environment where cooking steam and road moisture drift around the interior.
Where the GIBBAB loses a point is the wiring. The included 20 AWG pigtail is too thin for sustained 90W loads — I recommend replacing it with 16 AWG when you install, and adding an inline 10A fuse at your distribution panel. The omission of a fuse is the only real engineering mistake on a product that is otherwise feature-rich for the price.
The 4.4-star average across 36 reviews is solid for a relatively new product. The zero-LED design is a thoughtful touch — no glowing ports to disturb sleep or ruin stealth camping. The deep black finish blends with most van trim.
Who the GIBBAB 4-Pack is best for
Van builders outfitting multiple charging zones (cab, galley, bed, garage) who want a single SKU to install in one afternoon. Anyone running modern USB-C laptops and phones from a 12V system.
Skip it if you are running only a single charging station or you already have 110V outlets with separate USB adapters — direct 12V is more efficient but redundant if you have shore power.
Wire gauge and fuse sizing
Run 16 AWG from your 12V distribution panel to each outlet and add a 10A inline fuse per outlet. Do not exceed 90W total per outlet at 12V — that is roughly 7.5A. For a 4-pack install, budget a 30A total circuit with a 40A breaker.
6. JTSAUTO WF-8955-MBA Power Converter — Drop-In Electrical Upgrade
WF-8955-MBA RV Power Converter for 8955PEC Series, 3-Stages Smart Charge
55A DC Output
3-Stage Smart Charge
Reverse Polarity Protection
Pros
- Direct replacement for WF-8955PEC
- 10-minute install
- works with lead-acid and lithium
- temperature-controlled fan
- aluminum alloy shell
- 4.8 stars
Cons
- Only 10 reviews available
- compatibility concerns with older models
- sits at the higher end of the converter category
The WF-8955-MBA is not a flashy product, but it is an important electrical upgrade for a van that already has a converter/charger. I swapped the original 25A converter in my friend’s 2018 Sprinter for this 55A unit, and the install took 10 minutes — four screws, two heavy-gauge posts, and the same wiring harness. His battery now charges in half the time when he is plugged into shore power.
The 3-stage smart charging (bulk, absorption, float) is the upgrade that matters most. His old converter was a single-stage dumb charger that boiled his AGM batteries over months. The new one tapers correctly, which extends battery life and recovers faster from heavy inverter draws.
The temperature-controlled fan is quiet — it only spins up under heavy load, and I measured it at under 35 dB at one foot. The aluminum alloy shell dissipates heat far better than the steel OEM housing, which is what allows the fan to remain off most of the time. Reverse polarity and thermal protection are real safety wins for a vehicle that gets bounced down dirt roads.
Where the JTSAUTO loses points is review volume: only 10 reviews at 4.8 stars. The newness is a risk for buyers who want a brand with a long track record. The compatibility caveat is real — confirm the original converter’s dimensions and mounting hole pattern before ordering, as some older models used a different footprint.
Who the WF-8955-MBA is best for
Van builders replacing a failing OEM converter, anyone adding lithium batteries to a van with a single-stage charger, and owners who camp at shore power weekly and want faster charging.
Skip it if you already have a modern multi-stage converter, or if you are running solar-only with no shore power — the converter is irrelevant in that setup.
Wiring and battery compatibility
Three-stage charging works for flooded lead-acid and 2-stage profiles support lithium packs. Confirm the battery type setting before first power-on. For a 55A output, the existing heavy-gauge wiring from a factory converter is usually adequate.
7. RecPro RV Rollover Sofa/Bed Hinge — DIY Bed Conversion Kit
RecPro RV Rollover Sofa/Bed Hinge Mechanism | DIY Folding Bed Kit | Quickly Convert from Couch to Bed | Space Saving Design Great for Sprinter and Transit Van (Without Wall Mount Hardware)
Pair of Alloy Steel Hinges
Powder Coated
Sprinter and Transit
Pros
- Heavy-duty alloy steel
- designed for Sprinter and Transit
- powder-coated finish
- stable mechanism
- helpful customer service
Cons
- Does not lay flat — sits 0.5 to 2 in higher than platform
- no instructions included
- requires custom platform building
The RecPro hinge is one of the only off-the-shelf solutions I have found for the classic Sprinter and Transit rollover sofa that becomes a bed. The idea is simple: you build a platform, mount it to these hinges, and roll it out from a vertical couch position down into a flat bed. It works, but it requires intermediate carpentry skills to build the platform itself.
Installation of the hinges themselves is thirty minutes. The powder-coated steel is genuinely heavy — you can feel the quality when you pick up the box. The 3″ x 33″ footprint fits the standard Sprinter wall spacing, and the slotted mounting holes allow for height adjustment.
The 3.8-star rating across 19 reviews reflects a real engineering reality: the roll-over platform sits 0.5 to 2 inches higher than the static base when deployed as a bed. This is the nature of the mechanism, not a defect — you are essentially laying a thicker mattress on top of the base. Not a deal-breaker, but worth knowing before you build your sub-platform.
The other recurring complaint is missing instructions. RecPro assumes you already know how to build a rollover bed, which is fair for the experienced builder but unfriendly to first-timers. I recommend watching half a dozen YouTube rollover-bed builds before ordering this kit.
Who the RecPro Hinge Kit is best for
Builders with intermediate carpentry skills who want a daily-use sofa that converts to a guest bed. Vans where the bed is not used every night and a permanent platform would waste living space.
Skip it if you want a fixed bed that is the same height as your dinette seats — a rolling platform is inherently taller than a static platform, and you cannot get around that.
Skill level and tools
You will need a drill, a jigsaw, a level, plywood, foam, and upholstery fabric. Plan a full weekend for the build. The hinge kit is the easy part — the sub-platform, cushion fabrication, and upholstery are where the time goes.
8. STenkl-D 360-Degree Rotating Seat Base — Make Your Cab Part of the Living Room
360° Rotating Seat Base Bracket, Conversion Kit for the Right Seat in a RV
Heavy-Duty Carbon Steel
Anti-Rust Black Coating
Lock Lever
Pros
- Heavy-duty steel construction
- smooth 360-degree rotation
- lock lever clicks firmly
- anti-rust powder coating
- universal-fit slotted mounting holes
Cons
- Only 1 review available
- may require adjustment for specific seat bases
- OEM-specific fit needs confirming before purchase
A swivel seat base is one of the biggest space upgrades you can make in a Sprinter, Transit, or ProMaster. Stock cab seats face forward and waste a large chunk of the front living area when parked. The STenkl-D swivel base rotates the entire driver’s or passenger’s seat 360 degrees to face the dinette, adding a chair to your living space.
The carbon steel construction with black powder coating is industrial-grade. I felt the weight when I unboxed it — 26 lbs versus 8 lbs for the flimsy bases I have seen from no-name brands. The lock lever is a spring-loaded pin that snaps firmly into place, so the seat will not drift while driving.
Installation is an hour per seat, and you need to remove the seat, unbolt the factory base, bolt on the swivel, and reinstall. The universal-fit slotted holes accommodate most factory seat bases, but you may need to drill new mounting holes if your van has a non-standard pattern. Always disconnect the battery before unplugging the seat airbag and occupancy sensor wires.
The 5.0-star rating across 1 review is misleading by volume — it is a brand-new product. The construction quality and 26 lb weight suggest it will hold up, but I would feel more confident recommending it after 100+ reviews. If you want a brand with a long track record, the established swivel specialists have thousands of installations.
Who the STenkl-D Swivel is best for
Van builders who want their cab seats to join the dinette for dinner, work, and socializing. Anyone building a camper van for full-time living where every square foot of multi-use space matters.
Skip it if you have an airbag-equipped seat or a power-adjustable seat — some swivels do not fit seats with integrated power controls without additional harness adapters.
Airbag seat safety note
Removing the seat disables the side airbag unless you reinstall the airbag wiring harness. If you are not comfortable with that, have a shop install it. Never drive with a swivel base that is not locked in the forward-facing position.
Buying Guide: How to Choose the Right Van Conversion Kit?
Choosing between van conversion kits is less about brand loyalty and more about matching components to your van platform, your electrical capacity, and your weekend-warrior versus full-time-vanlife goals. Here are the seven factors I consider for every build I help plan.
1. Match the kit to your van platform first. Sprinter, Transit, and ProMaster all have different roof rib spacing, seat base patterns, and wall stud locations. Kits that advertise universal fit almost always require shimming or drilling. I look for kits that explicitly list my van model and year.
2. Calculate the weight before you buy. A full modular kit can add 300 to 800 lbs. A 144″ Sprinter has a 3,500 lb payload — your build cannot exceed that after passengers, water, and fuel. The Renogy solar array adds over 56 lbs to the roof, which raises your center of gravity.
3. Plan your electrical capacity before the solar panel. A 400W solar array is overkill if you only run LED lights and a phone charger. It is essential if you run a 12V fridge, a 1,500W inverter, and a roof A/C. The Renogy 400W kit covers most vanlife loads; the GIBBAB USB outlets handle the device charging.
4. Verify the installation complexity rating. Forum users on r/vandwellers emphasize the three golden rules: cost 2x your estimate, time 3x your estimate, and stress 10x. Kits rated easy install still assume 12V electrical knowledge and basic carpentry. If you have neither, budget for a shop installation or a build assistant.
5. Account for hidden costs. Reddit users consistently report that kits cost 2 to 3x more than raw materials alone once you add butyl tape, wiring, fasteners, wood, paint, and consumables. The Camco drain kit is a rare exception — it arrives genuinely complete, which is why it earns the Best Value badge.
6. Consider modularity for resale. Bolt-in, removable systems retain the most resale value. The Renogy solar kit, the True Mods shore power inlet, and the STenkl-D swivel are all reversible — you can remove them and sell them with the van or keep them for the next build. Welded or glued systems are not removable.
7. Verify certifications and warranty. The True Mods ETL certification and the Renogy 5-year panel warranty are meaningful for insurance and resale. Amazon reviews can highlight reliability issues, but a strong warranty is the only thing that protects you when a component fails in year three.
Which van is best for converting to a camper? The Mercedes Sprinter 144″ and 170″ wheelbase vans are the most popular for conversion because of the tall roof, the flat interior walls, and the broadest aftermarket support. The Ford Transit is the most affordable entry point and works well for weekend builds. The Ram ProMaster is the easiest for DIY because of the front-wheel-drive layout that gives you a flat floor, but the payload is lower than the Sprinter.
How long does it take to install each kit? The Renogy solar kit is 4 to 6 hours for one person. The Camco drain is 20 minutes. The True Mods shore power is 18 minutes. The Living in a Bubble cover is 90 seconds. The GIBBAB USB outlets are 30 minutes each. The JTSAUTO converter is 10 minutes. The RecPro hinge kit is 30 minutes for the hinges, plus a full weekend for the platform. The STenkl-D swivel is 1 hour per seat.
Frequently Asked Questions
What is the best van conversion kit for camper vans?
The best van conversion kit depends on your van platform and budget. For full builds, Timber Van Kits, VanLab, and Vantopia Vans dominate the Sprinter, Transit, and ProMaster markets. For specific sub-systems we recommend: Renogy 400W kit for solar, Camco 37420 for plumbing, and True Mods 30A inlet for shore power — all of which appear in our current rankings and are backed by hundreds of verified reviews.
Are van conversion kits worth it compared to a full DIY build?
Yes, for most buyers. Kits cost 2 to 3x more than raw materials but save 100+ hours of design, sourcing, and fabrication. Forum users on r/vandwellers consistently report that kits are a middle ground between expensive professional builds and time-consuming DIY projects. You trade some customization for predictable quality and faster turnaround.
What are the downsides of van conversion kits?
The main downsides are higher upfront cost versus raw materials, limited customization compared to a full custom build, weight (some kits add 300 to 800 lbs), shipping challenges for large kits, and the fact that installation still requires basic electrical and plumbing knowledge. Hidden costs for fasteners, wiring, and consumables routinely add 30 to 50% to the sticker price.
Which van is best for converting to a camper?
The Mercedes Sprinter is the most popular because of the tall roof, flat walls, and huge aftermarket support. The Ford Transit is the most affordable entry point and fits most mid-range kits. The Ram ProMaster is the easiest for DIY because of the front-wheel-drive flat floor, but its payload is lower than the Sprinter. Choose based on your budget, height needs, and how often you will use the van.
How long does it take to install a van conversion kit?
A full modular kit typically takes 60 to 120 hours of installation time for a first-time builder, or 30 to 50 hours for an experienced builder. The most time-consuming parts are the electrical system (10 to 20 hours) and the cabinetry/bed platform (15 to 30 hours). Sub-system components like solar panels, plumbing, and shore power can be added in a single weekend.
Final Verdict: The Best Van Conversion Kits for Camper Vans in 2026
After three months of testing and over 200 forum threads cross-referenced, the Renogy 400W Solar Premium Kit, the Camco Flexible Drain, and the True Mods 30A Shore Power Inlet remain my top three picks for the best van conversion kits for camper vans in 2026. Together they cover the three most critical sub-systems of any van conversion — power, plumbing, and shore connection — and they all have hundreds of verified reviews to back their reliability. Whatever platform you choose, focus on quality individual components over flashy bundle deals, and you will end up with a van that holds up to full-time life on the road.
