I am 6'3", 225 pounds, broad chest/shoulders, 36" inseam. No problems here and I have the 06 Adv. Package with the roof. I had a 1995 Explorer prior to my H3 and the H3 is much more comfortable, especially from a back support perspective. I sometimes wish for more lumbar support but this is because I have lower back issues. For a person without back issues, the support should be excellent.
The only true problem I have is when I have the rear seats down - it cuts down on the movement of the driver's seat (back and forth as well as seat back angle).
Regardless, entering and exiting are not issues.
