buying a class c

Class A versus Class C, mostly a matter of taste and intended useage. Some like the huge expanse of windshield in an A, some prefer the shade of an overhead bunk in a C. Some think a C is easier to have serviced and has greater head on collison protection. My prejudice is that a larger A is better for a mature couple that are mostly interested in touring. A 27 foot or longer C is more for family camping, casual use for local events, and occasional touring. Try driving and simulate living in both types. Don't be over-awed by size.
