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 ...
I'm not tall. But I will put in a plug for my Class C, a Sunseeker 2300 on the Chevy chassis. It has a residential size queen bed, 60x80. You didn't ask about beds, but I thought you might be interested in that aspect too.
