Good morning. I am new here and have a question. I live in my 5th wheel, and the 12 volt system no longer works. My fridge is in that system. It will normally run propane or electric, but since the 12 volt system doesn't work, my fridge won't work...is there a way to bypass the 12 system and put the fridge on its own? Please! Somebody help me!!!!! (Said in a screaming voice).
