We do allow Clamshell and Teardrop Campers that meet the self-contained requirements (below) with an exception:

You may not use the outdoor kitchen to cook.
  Our members will eat a lighter fare (sandwiches, salads, etc.), dine before they arrive to the Host location, or even eat at the Host venue.

The self-contained requirements:  Your RV must have an interior toilet and built-in holding tanks (or a bladder) for waste water. Porta-potties are acceptable but must be dumped off-site at an appropriate facility. The dumping of any gray water on Host properties is prohibited. You must have interior cooking facilities. Sorry, no tents of any kind allowed.  Prohibited: Tents, campers with tent pop-outs, mini-vans, sleeping in cars or trucks
