Well so do I and I can get my 1 to 1 scale 6 ft span golden eagle (made in 1992) in there no bother with the front seat folded forwardsand the backs folded as well. I suspect even a 'mighty barnstormer' wing would fit. as for sleeping I haven't done that but the front seat looks OK if folded back all the way and of course slid fully back before that. Happy flying and camping anyway.Thanks for the replies - to answer the question, I fly model planes - a few of which are quite big, so the more loading space the better. Also, I occasionally camp over at a flying site for night flights & social. I've been using a tent, but if I could just crash out in the car, then that would be easier.
I'll have a look at the links posted by plancast.
