Building a van for California

A van sees a great deal of this state, because most of what the agencies document is road. Titus Canyon is rated for two-wheel drive with high clearance, the Bradshaw Trail is a graded dirt road, and Soda Lake Road through the Carrizo Plain is open year round. Ride height, tires and a plan for washboard matter more than a transfer case.

Plan around heat and the law. Death Valley summers often top 120°F in the shade with overnight lows in the 90s, so ventilation, shade and refrigeration decide whether the desert season starts in October or in December. In winter, Caltrans R-2 controls let a four-wheel or all-wheel drive van through on snow-tread tires, but it still has to carry traction devices.

The full guide to overlanding California

What a Sprinter builder does

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

  1. 01Insulation, wall and ceiling panels, and flooring
  2. 02House battery, alternator charging, solar, inverter and shore power
  3. 03Roof fan, heater, and sometimes air conditioning
  4. 04Fresh and gray water, a sink, and sometimes a shower and water heater
  5. 05Bed, galley, seating and storage
  6. 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.

  1. 01Decide between a shop's standard layout and a custom build. Standard layouts are faster, and the shop has already solved their problems.
  2. 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.
  3. 03Ask how the electrical system is protected and documented, and whether the components can be serviced on the road.
  4. 04Ask how cabinetry is fastened to the van. Furniture that is only screwed to thin wall panels works loose on rough roads.
  5. 05Ask how added seats and seat belts are engineered and anchored if anyone rides behind the front row.
  6. 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.

  1. 01Model year, 144 or 170 wheelbase, roof height, and two-wheel, all-wheel or four-wheel drive
  2. 02How many people sleep in it and how many ride in it
  3. 03The seasons and climates you travel in
  4. 04Whether you need to work from it
  5. 05What goes inside with you: bikes, boards, dogs
  6. 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 California?

From Brawley at -113 feet to Mount Whitney at 14,494. Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
