How to Choose a Van for Your Conversion
Buying the van is the most expensive decision in your build—and the hardest to undo. Before you scroll marketplace listings at midnight, decide what your conversion actually needs to do.
High-roof vs standard roof
If you want to stand inside or mount a fixed bed width-wise, high-roof Sprinters, Transits, and Promasters are the usual answer. Standard-roof vans cost less and park easier but force compromise layouts and crouching.
Wheelbase and length
Long wheelbase adds floor space for showers and fixed beds. Short wheelbase fits urban parking and mountain roads. Measure campsites you plan to use—some have length limits.
Diesel vs gas
Diesel vans often get better mileage loaded; gas vans can be cheaper to maintain in North America. Consider where you will service the vehicle on long trips.
Mileage and rust
Commercial fleet vans may have highway miles but door dings and idle wear. Inspect wheel arches, rocker panels, and undercarriage. Rust repair eats build budget fast.
Popular platforms

- Ford Transit — wide aftermarket, multiple roof heights
- Ram ProMaster — front-wheel drive, square walls for cabinetry
- Chevy Express / Ford E-Series — older platforms, lower entry cost
Bring a magnet and moisture meter to inspections. Bondo hides rust; a magnet that does not stick is a red flag.
