Just for the record, we discovered the same leak (under the kitchen sink/hot water heater area), as described in the first post, this weekend. Carpet was soaked. Also, our dual propane valve would not switch to the door side tank for some reason. Had to move the full tank to the other side so we could run heater. Kind'a disappointed... It's funny that all the problems that everyone has described on this forum has happened to us. Hopefully, the factory is taking notes. Anyway, not complaining just letting those that have the cyclone have a head up.
Happy camping.
