Why a class A gas over class C?

Our first rig was a 24' Fleetwood "C" class. We had it one year and mostly did weekend trips. We then drove it to Omaha to see our daughter graduate, we lived in Ca. at the time. Going across Wyoming and Nebraska the winds were very bad and we got blown all over the road. My wife tried driving and only made it about 50 miles before she had me take it back, it was too much for her to handle. The week after we got back it was sold for a 33' Class A. The different in handling was tremendous. I'd say drive them both and compare for yourself. One other thing that I didn't see anyone mention. In the "C" class when I was driving at night, I would get a reflection from the white line on the overhang, almost like a strobe light. It was very distracting, to the point I would avoid driving at night. Good luck with what ever you decide.
