Neither one. When we moved from a fifth wheel we thought we were going to a class c. But after sitting in the front seats of several we realized how crowded and cramped it was. My CEO/Navigator likes being able to move from the cab to the living area while I'm driving and she found it difficult if not impossible in the c. Sit in the living room or dining area and try to see out the windshield of the c then look out the huge front picture window in a class a. There's no comparison. There is usually much more storage in a class a compared to the class c. Some will want a class c because it is smaller and can get into more campgrounds. But, because of the hood/engine area a class a can be the same size with more room inside. And finally, the class a's we looked at did not cost much more than a class c.
