I'm 6'5" tall... with a 36" inseam. You're just not looking at the right class C moho. My Kodiak chassis class C has more than adequate room in the cab... everywhere. It's really comfy... AND it has a rear island queen!

and my '95 Ford E-250 B-van works fine for me... I actually prefer driving it to my cars because it's so comfortable.
