owner manuals

I have a Carriage trailer and contacted them when they were still in business and asked for electrical and plumbing layouts. They replied that they didn't have them which I thought was BS. I think they wanted to keep the info to themselves and maybe their dealers so you had trouble repairing the unit yourself. I had to figure out the electrical by shutting off breakers and opening boxes to trace cables. Same with the plumbing as I took out dividers in the storage areas to see where the pipes went. Traced the coax by colours (thankfully they used 3 colours of coax). If you have a basic understanding of how most trailers are put together you can figure it all out. I found my coax was very similar to other makes of trailers. I have the owners manual for my trailer but it is useless.
