The Class C motor homes (Sprinter is an exception, but I am not interested in diesel) that I have seen are difficult for me to drive due to my 6'2" frame, as the "dog house" cuts back the rear motion ...
Another vote for the Chevy. DH is 6'4" and felt very cramped when he tried to test drive a Ford. The Chevy has a little more comfortable for him and on our RVision there is enough room behind the drivers seat to recline some.
He is also able to walk around our unit and stand up in the shower. Not enough room to stretch but he doesn't bump his head. :E
