Danya, wmtire did a superb job of getting you on the correct track for hot water.
I'd like to address your photo of the white colored valve you said the dealership told you went to the outside shower. I don't believe it does.
To supply the outside shower, there needs to be two plumbing lines going to it. Hot and cold. To control flow to the outside shower, the valve would somehow have to be able to shut off both the hot and cold water supply. This valve does not do that.
The white valve in the photo is the winterizing valve. (also sometimes called the fresh water tank bypass valve). With the valve positioned as it is in the photo, your system is able to draw fresh water from the fresh water tank via the on board pump.
You would turn this valve 1/4 turn when winterizing to draw antifreeze from the antifreeze connection with the on board pump. (Refer back to wmtire's winterizing diagram post). This allows you to inject antifreeze into the plumbing system without having to pour antifreeze into the fresh water tank. (something you don't want to do)
I believe the dealership gave you incorrect information about the white valve.
