It was made for both short and long bed trucks. Just depends on if it has the rear storage compartments or not. Center of gravity wise either version will work on a 6.5 ft bed.
These were smaller , 86 inches in width I believe vs. 96 for most full size campers and very light weight. No bathroom or shower but had a big closet/storage room with door to put a porta potti in.
Just look for the usual water leaks and subsequent wood rot in the frame of these. I see them around here on Craigslist every once in a while for 2-3k in good shape.
