We have not used our 2005 Granite Ridge in a couple of years. We are going through the camper fixing one thing at a time. I recently hooked up the water in city mode with a 1/4 turn from our outside house faucet.
The shower head leaked so I replaced it with one from an RV store that shuts off at the shower head. Now I am finding that the shower handles do not work at all. I took the decorative handles off to see if the plastic nuts were worn and the nuts blew off and water free flowed from both hot and cold.
I guess I need to replace the base and the faucet handles. But I can't figure out how. I have attached a photo of the faucet base(stock but similar to ours) and a floor plan showing there is a cabinet behind the shower wall.
