We do not allow it. When you run the sewer hose under the rig to reach the sewer connection there is no way to remove the sewer hose that doesn't leave a trail of waste when you pull the hose back out from under the RV. It also gives others the idea that if that rig can go in backwards, they can as well because it might give them a better view or will somehow be a better placement. But this then means their doors open into their neighbors yard which is unacceptable. Our sites are constructed for the rigs to go in one way, and that's the way we require the rigs to park. So it really does depend on the rules of the park you choose. BTW, if you ask us in advance, we will tell you our rules so it won't be a surprise.
