Recommendations for Parking Surface for Diesel Pusher

I had some pretty bad soil under where I wanted to put ours. So I put down some geofabric (you get it at a contractor supply) and put a few inches of recycled asphault down. It's like cement. I've put the jacks down for extended periods without pads and been parking there for a few years now. No ruts no soggy mess...nothing. It doesn't turn to mud or get soft. Its been great.
