I agree with Roy. Manuals are not very specific, devoid of finite info and may cover many years of a run of that model along with several other 'close' models. My used Lance came with a pile of separate sheets for all the appliances but no wiring schematic. When I needed a schematic of the side of my Lance I called the factory and they sent me the build sheets for that specific model to find out where the framing was under the skin. The stainless steel screws for my low budget rip stop awning L bracket found the exact placement of all the wood side supports which were not at all where I thought they would be.
I think it would be good to have someone (not me) compile all the factory manuals for campers past and present on this very forum. I've copied and mailed my manual several times for owners who did not receive one with their camper. If someone with scanning skills had the originals, we could have a good library of informative manuals available for download. Just a reminder: not me.
