if you can try and lift door off tracks and remove and replace. its just a hollow door like any normal bedroom door in a house.

Go to an RV parts store for a winterizing bypass kit for the water heater. Use POTABLE RV antifreeze and follow the instructions on the bottle. Drain all the water out of the water tank. Install the bypass kit on the water heater if it doesn't already have one. Put the water heater in the bypass mode. Add the antifreeze to the water tank. Open every water faucet including the shower head one at a time until antifreeze is present. Do this for hot and cold on every faucet. Once that is done, turn off the water pump and open all the faucets. That's all there is to it. Rember... DO NOT use automotive antifreeze. It will kill you.

You have to mechanically trace the positive wire to see where it is grounding out against the metal frame. Usually it is where it rubbed.
Sometimes it is easier to just run new wiring to it.

With electrical it is a matter of spending the time eliminating the variables. If a fuse is blowing you are more than likely dealing with a short to ground. It could be a staple through a wire or a place in the wire where the sheathing has rubbed through allowing the hot wire to contact a ground source. It could also be a bad ground which is allowing resistance to build and ultimately blowing a fuse. First, determine everything that is on the circuit (which lights). Second, inspect every inch of the circuit for bad connections, loose grounds, and damaged wires. If nothing is found then start eliminating one fixture at a time to see if you can find the culprit. If you disconnect the last light in the series and the fuse still blows. Reconnect the last light and move on to the next light and so on until you find the problem. It can be time consuming and unfortunately there typically aren't any wiring schematics for RV's.
