I'm 6'7 also. Used to have a Jayco bumper pull that was tall enough inside. Have also had a Grand Junction 5th wheel that had plenty of room, even in the shower and bedroom. Tightest place in the rig was at the very front in the closet and that wasn't terrible. Now have an 05 Alfa See-Ya with 7 foot ceilings and I can wear a ball cap under the ceiling fan without problem. I'm not going to advocate any of them, they work for us, but may not for you. Go try the rigs, the shower tends to be the hardest for me to fit, so that's my litmus test.
