I am 6'4 and the only real issue I have is the bathroom door height is about eye-level, if that.  Otherwise it sits taller than many traveltrailers I've been in.  The side height is probably in the 6'2" range so you'll still have to duck to get in the door, but c'mon, you're used to it!  I wouldn't want to live fulltime in the thing, but for a week or two at a time I have plenty of headroom.
