A van can drive a great deal of Arizona, and the agencies are clear about where it cannot. The Park Service says cars, minivans, crossover SUVs and RVs are not the right vehicles for Grand Canyon-Parashant. Tuweep caps a party at 22 feet end to end, and Organ Pipe bans vehicles over 25 feet on Ajo Mountain Drive.
Build for the heat above all. NOAA puts the southern deserts between 105°F and 115°F in summer and a typical year at 38 days of 100°F or more. Ventilation, insulation, shade and battery temperature limits come first with a builder, then where two spare tires live.
A conversion is a small house on a moving, flexing, weight-limited platform. The builder insulates and lines the shell, installs the electrical system, plumbing, heat and ventilation, builds the bed, galley and storage, and cuts the holes for windows, fans and vents that you do not want to get wrong.
Some shops build complete vans to a set floor plan. Others build to order, and a few will take on partial work such as electrical only.
A typical conversion includes
01Insulation, wall and ceiling panels, and flooring
02House battery, alternator charging, solar, inverter and shore power
03Roof fan, heater, and sometimes air conditioning
04Fresh and gray water, a sink, and sometimes a shower and water heater
05Bed, galley, seating and storage
06Windows, racks, ladders, awnings and exterior lighting
How to choose a van builder
Floor plans are easy to fall for. The questions underneath them matter more.
01Decide between a shop's standard layout and a custom build. Standard layouts are faster, and the shop has already solved their problems.
02Ask what the finished van weighs with water and gear. Sprinters are sold in several gross weight ratings, and a heavy build on the lightest chassis leaves little margin.
03Ask how the electrical system is protected and documented, and whether the components can be serviced on the road.
04Ask how cabinetry is fastened to the van. Furniture that is only screwed to thin wall panels works loose on rough roads.
05Ask how added seats and seat belts are engineered and anchored if anyone rides behind the front row.
06Get the scope, price, payment schedule and delivery date in writing.
What to have ready before you ask for a quote
The van you order decides what can be built in it, so it helps to talk to a builder before you buy.
01Model year, 144 or 170 wheelbase, roof height, and two-wheel, all-wheel or four-wheel drive
02How many people sleep in it and how many ride in it
03The seasons and climates you travel in
04Whether you need to work from it
05What goes inside with you: bikes, boards, dogs
06A budget range and the date you want to be traveling
Questions people ask
Do I need to own the van before I contact a builder?
No. Many builders would rather talk first, because the wheelbase, roof height and drivetrain you order decide what can be built. Some shops can also source a van.
How long does a Sprinter conversion take?
A full custom build is usually measured in months, plus whatever wait the shop has before it can start. Standard layouts are quicker. Ask for both numbers.
Should I get the 144 or the 170 wheelbase?
The 144 is easier to park, turn and drive on tight roads. The 170 gives you room for a fixed bed and a real galley without compromise. Think about where you will actually drive it, then about how you want to live in it.
Can these builders work on a Ford Transit or Ram ProMaster?
Many do. If you are on another platform, say so in the form and we will look for shops with that experience.
How high is Arizona?
From Yuma at 141 feet to Humphreys Peak at 12,633.
Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
