One thing to consider between class a and class c is the size and cost of new tires. Tires on my class are $200 a piece and easily found. Class a motorhome tires are generally larger, more difficult to locate and cost more than twice as much.
I called my local ford dealership to see if they can change the oil in my rv. They responded with "how big is it". So that's another plus of having the class c. When I told them, they said they could. Of course they might of been able to do a class a of the same length, but I'm thinking that if I go the class a route, the. I would get something bigger. My boss had two class a's a couple of years ago and just got a class c. He loves the c more. Said it was easier to operate.
