Hi Joe: We hope you have a great time when you visit. You seem undecided at this point whether a Class A or Class C might work best for you. Ultimately, it will be your decision, but here are a couple of things to keep in mind. If you are traveling alone, then a 24 foot Class C might be big enough for you. It is easier to park, and will better fit into shorter camp sites that are typical in state parks and on federal property. If traveling with more than one person, a Class C usually has more sleeping positions than a Class A. I have not checked rental fees, but I believe that a rental fee for a Class C would be less expensive than a Class A. We hope to hear more of your planned trip in the future.
Best wishes
