For our maiden voyage we decided to stay close to home to make sure that everything functioned properly. After initially hooking at the campground, Rebecca frantically comes running outside saying that there was a flood in the bathroom. Apparently, the dealer forgot to shut off the faucet. Everything worked great except the hot water. Sean thought it was probably still winterized and on bypass but could not find the bypass valve anywhere. Looking through the owners manual was not much help. We decided to call Good Sam. They told us that it was probably the control board and that our unit did not have a bypass valve.
