Hello, I have a 2003 Dutchman Supreme fifthwheel. It has been stored for the last few months, prior to that, we were living in it. We just moved it to a new location and was setting it up to stay in again, plugged it in, electric came on but shut off after just a few minutes. Now there is no power at all. We have checked breakers but none were flipped. At a loss and can't afford to hire anyone to check it out for me. Help please!?!?!?
