Well you really need a self contained rig or they want you to camp up front by the outhouses and such. Certainly not something we would want to do with all the dust from the road and the noise from all the vehicles going by up there. Not a very attractive option at all, but some folks do it for whatever reason.

Yes!! They require/ask that you camp within so much distance of the vault toilets (don't recall what the distance is) IF you aren't self contained with your own waste water/bathroom facility. But I see many tent/car campers during the winter season there.

Yes. Remember that you will still have to pay the same fee as any other campers.

Yes but I wouldn’t try it until late Fall. It’s HOT right now!
