One consideration for us is the living space you lose in a C. Essentially, the front seats are not very usable when parked.
We had a 31' Suncruiser for 28 years, and gave it away last December to a homeless vet and family. In April we rented a 30' Cruise America for 10 days, and in September purchased a 31' SunStar.
2 other things about Cs vs As. For me at 6'4" and 220 lbs, the driving position was very uncomfortable since the seat would not slide back far enough. Too close to the wheel, and too upright. My wife said that I looked like I was driving a go-kart. And I had to take off my shoes to fit my feet in to work the pedals.
The extra width behind the cab was also a concern, although I guess we rather got use to it by the end of the trip.
