I operate a home inspection business and often find myself between appointments wanting a place to type reports or just relax and eat lunch. I just replaced the motor and transition in my cargo van so it looks like I will be using it for a while. Lets make the best of it. Every vehicle interior is different with a little insulated foam board, a hot glue gut, and some door skins, you can make a template in which to cut plywood to make a nice interior. Please note: this is something to enjoy while safely parked. Do not drive on these seats as they are not approved for transportation safety.
Step 1: Step 1
Clean out your space and find some objects you can sit on and things to represent a back rest so you know how your body fits in the fan. I used my daughter's booster seat and some bricks. I showed me not to put the rear seat too far back or I would bump my head on stuff. Get a basic idea on how you will fit and then its time to foam it out.
