What fits
- Standing: 2.17 m floor-to-headliner, about 2.10 m after a typical 7 cm floor and ceiling build-up — stands an adult up to about 2.05 m.
- Bed across: 1.87 m between the walls, about 1.81 m after 6 cm of finished walls — sleeps a 1.75 m adult transversely with 5 cm to spare.
- Parking: 2.76 m tall outside — over 2.0 m, so underground garages and most height barriers are out (French motorway class 2).
- Payload: about 1,370 kg — 3,500 kg gross minus 2,130 kg kerb. After a typical 600 kg build and the EN 1646-2 two-person reserve of 155 kg, roughly 615 kg is left for water, gear and people.

Who makes this
I'm Vladimir. I'm planning my own conversion, and none of the tools I tried could tell me whether a layout would fit or what it would do to the rear axle, so I made this one. I work on it alone. If something's wrong or missing, write to me — the address goes to my inbox.
