IMHO, the best class C is a Lazy Daze unit. They make a class C exactly how you want if. If you stumble across a used unit to your liking, be sure to check it out. Lazy Days makes super quality class C RV's to order. Also, buying a former rental RV may or may not be a good fit for you. That said, I think the former rental from a large company that refurbs them is only a good option for a minority of people. Still, worth a look if you have a local Cruise America or El Monte.
Happy hunting!
