Heh JCZ,
First problem is getting into the camper..standard door is 5'3". No problem getting in, but I've got binged a couple times going out! Probably being tall, you are more aware than I of such things.
Right inside, center isle, is 6'6". Turn left toward the dinette, right at the sink, it is 6'3". Turn right, the ceiling is 6'9" at the steps going up to the bed. The ceiling in the bath is about 6'4".
The bed is a standard shaped queen, and standard width, but is a couple inches shorter.....room for your feet however.
Love our 5.0....easy to hook up, and easy to pull. But, since the pivot point is over the axle, it's different in the way it turns (trailer radius is shorter than truck), and it backs differently....just a little learning curve.
