Shower

Premiere.....If you have an outside shower. Make sure the water is turned off at both shower knobs on the outside unit, not just at the shower head. Often, if the knobs are left on, it will cause funny things to happen with your hot water.

Thanks for the advice. Appreciate all your input.
Just purchased the the motorhome, so not sure what the
previous owner did or did not do.
I will definitely check it out.

.... have hot water to everything except Shower. Any suggestions?

Just learn to take cold showers!!!!!

Seriously, I assume up until now you had hot water at the shower. If that is the case, then back track to the last time you did something to the water system-maybe winterizing. Probably a valve left in the wrong position.
Also, could possibly be something with the hot water valve at the shower. A washer could have come loose and lodged itself against the seat closely off the water flow.

Are you saying you have water coming out with just the hot on, But it's cold? Make sure the outside shower valves are turned off. If no water at all then you have a water manifold with the shower hot water valve turned off. Should be located near your water pump.

Closed valve somewhere
Probably used during winterizing, to same on RV water system antifreeze
