Hey There,
Sorry for not responding sooner. I didn't see this until now. Our Thomas Vista (5 window)has 14' behind the driver's seat. I'm 6'2 and so also trying to maintain every 1/8" of height. I'm using 5/16" T&G pine for the ceiling and put down 1" foam and 1/2" ply for the floor. Looking for thin flooring- hopefully cork. If I end up with 1" of head clearance I'll be happy!
Look for a bus that has a small rise from the driver's window to the rear ones- they have more headroom. I like the Thomas because the ceiling was screwed on rather than the Blue Birds that use rivets- easier to demo.
Have fun!
