Regarding your question on class C verses Class A; I think its a matter of preference until you get to the larger units. Then a Class A is definitely the way to go. When we first started looking we thought Class C. The DW thought she would feel more comfortable driving it (feels smaller when your in the cockpit). We decided to go with a class A since I figured I would be doing most of the driving anyway, and the class C is no comparison to the picture window view of a class A. As it turns out, the DW only drove our 34' unit for about 15 minutes, and has yet to get behind the wheel of our new one. As far as purchase, I might suggest a dealer. You may pay more in the long run, but most units are warrantied, and they can get you financing nowadays to fit any budget. You also can be less concerned about the condition of the equipment since the dealers usually go through them pretty good before they go on the lot.
