You will get better responses IF you would post Year/Make/Model of your RV
RVs have SAME 120V AC System as multi-million dollar structures (even those middle income ones too)
RVs have 12V DC System which is not a complicated scheme
RVs use similar appliances etc
And many RV MFGs don't have/provide plumbing/electrical diagrams.
And NO---Mobile Traveler is no long in business (1971-1988)
Existing since the beginning of the 1970s, Mobile Traveler originally operated as a company that built Class C motorhomes. Initially utilizing the Dodge van as a base for their self-contained motorhomes that can sleep up to six occupants, Mobile Traveler products would later be built also on a Chevrolet and Ford chassis. Mobile Traveler produced of travel trailers during the 1985 and would manufacture 22-foot to 40-foot fifth wheel trailers from 1987 to 1988.
