My rv came with a good 10+ pounds of mauals. There are manuals for windows for manual's sake. Mirrors. The Door. Things I'll never even touch.. Invisible stuff (I should have put quotes around that it's visible if you contort properly) about he only thing that did not have a manual was the Drive shaft and U-Joints.
Like I said the RV book and the RV owner's handbook are good Generic owner's manuals. and all the "Stuff" you can download hte manual from the maker.
ONE exception.. A Dometic microwave (At least the model I have) Dometic did nto make it.. lousy goods did. So you download (Same model number) from LG. the LG name appears on the model ident tag however.. alas like all Lousy Goods products I've owned.. IT DID NOT WORK right.. I had to modify it and now it's great.
