I'm looking to do the same thing.
stopped working in Feb.
While I am a full timer, I am also not really mechanically inclined. It could be something as simple as a connection.
The final road to my RV spot was very bumpy and may have disconnected the line to both my heater and my fridge
. The fridge worked the first few days I was here, then quit. The heater hasn't worked since January but, since I'm fulltiming
here I have a plug in oil ambient radiator I use.
