I know that Yellowstone had pre-wired there travel trailers for AC even if the trailer did not have AC as I read this in a brochure of the trailers they were making in 1976.
What I am wondering is on which vent will I find the wire. I do not want to pull a vent at a time trying to locate it. Has anyone seen where they were located on the roof?
Do I have the last Yellowstone in existence
