owner's manual

Thank you everyone for your help. We are new RVers and just bought our first travel trailer, 2005 Frontier Explorer, no slide which had been sitting on a open storage lot for several years. Inside in very good shape so we took a chance, brought it home and found that the electrical system not working. Able to get outlets to work but still no lights, ac, frig etc. Also received a shock when touching parts of the outside of trailer when it's plugged in. Husband has been searching for a short but hasn't found it yet. He's been following the wires with a meter. Any suggestions? Mahalo
