Recommendations for Parking Surface for Diesel Pusher

Thanks for your replies. It looks like gravel is a pretty good surface, short of a cement pad. I was thinking of adding 3 or 4 inches of 1 inch stone to the gravel surface to improve drainage and to firm up the base. The coach has a GVWR of 36,400 so there will be some weight to it. Plus in the spring it can get a little soggy. Another friend put down some stone like I'm thinking of doing and then sprinkled concrete mix over the stone and it became a pretty solid surface over time.
