Re the diagrams.
I called, and asked, and called, and the dealer to get them for me, and emailed, and called to ask again.... kept being told that they didn't have any.
Finally I asked my warranty repair contact rep when in mid project, and he pulled together some for me.
I think they are worried that winnebago or someone will get ahold of them and copy their designs! Yeah,, like that's gonna happen.... some real proprietary stuff goin' on there....
