More than likley, you will be able to take a Class A (and even Class C's) to more parks than you can with any type of trailer. A lot of places cater to the motorcoach crowd. Just this past July 4th, we stayed at the Hilton Head Island Motorcoach Resort where it doesn't allow any type of trailers. It does allow Class A and C's with a minimum length limit. However, there is another place across the island where trailers are allowed. But so are coaches. Haven't seen a trailer only place. Well except for that Airstream Trailer Park I once saw...
