Well my surge protector saved me one more time.

WILDBILL308 - the exact same thing has happened to us. The park kept trying to say the pole was fine and that it must be our rig, which was not the case. We ran just fine by plugging into our generator. They couldn't fix the problem so instead of moving, they just charged us the dry camping fee and we used our generator as needed for the one night. Then same thing happened at a state park on the same trip and this time they found the problem in the pole.
