Sometimes a motel is a better deal than an RV park!
I called an RV park yesterday, the only one in a town I will be spending two nights in. $50/night, and NO public showers or bathrooms. The manager said that they will inspect my 'class B' when I arrive and make sure I have a 3" sewer hose...even though I have no interest in dumping there (and no tank to dump!).
I looked online, and there are 7 motels in the area in the $48-58 price range. Their locations are better, too. I think I'll pick one with a bathtub.
