So much to learn but thanks to you all we now have hot water.
Just make sure you turn the electric heating element off (the one on the front of the tank) whenever you drain the tank, or a better idea is to turn it off whenever you break camp. That way you won't forget it's on, the next time you plug into shore power (in case you don't have water in the tank).
You might want to make yourself some kind of tag (or similar) to remind yourself the switch is turned on.......so you will turn it off and don't burn up your electric heating element (which is a common occurance)
It sounds like your switch inside your trailer (if you only have one water heater switch inside), is for the DSI part of your propane. If you are going to be using the electric heating element side for now, and don't think you will use too much hot water when bathing....you can go ahead and turn the DSI switch off.
There is a little learning curve that we all have to go thru, but that's what this great forum is here for.
