I think DrewE nailed it for you. When we were looking at moving from a nice 5th wheel to a MH we looked hard at both A & C. We quickly moved away from C's for a couple reasons. When sitting in the passengers seat my wife's legs would have to be off to the side, not comfortable for her. Who would have thought. Also very limited travel from front seat to coach when moving. Class A just made things easier all around. But like Drew said take time and sit in the unit picture doing stuff. Even in the Class A make sure you can get to bathroom, frig, microwave with slide in.
