Living space is the amount of livable area (in square or cubic measurements) after conversion. Since vehicle width is limited by law and practicality, length is the biggest factor in the amount of space available, followed by ceiling height. The amount of available living space can be a factor in conversion difficulty, and larger vehicles increase parking difficulty.
Vehicles with passthrough (ability to move between the cab or driver's area and the back of the vehicle) have more available living space, especially if the front seat(s) can be swiveled toward the back.
Living space for different vehicle types:
- Large:Class A motorhomes, most buses, box trucks, step vans
- Moderate:Class B and C motorhomes, raised-roof vans, trailers
- Low: Standard-roof vans, pickup trucks with slide-in camper
- Very low:Cars, minivans, SUVs, pickups with topper
