With any large class C, be especially careful of the CCC (cargo carrying capacity). These coaches tend to be heavy and not leave much room to load your personal gear. Also, most large one exhibit some side to side roll and steering problems. I'd have the dealer fill the water and waste tanks and take it for a drive on city and highway roads. See if it drives OK or not.
