I see two possible problems, one is that I'm not sure what I'm calling the parts catalog will be the same as "build sheet"!
But when I want to know what parts they used and where, I love the parts catalog here:
https://catalog3d.winnebagoind.com/menu/Parts.htm
It lets us specify what Rv, what system and then zoom, turn . etc lots of ways to get a picture of what we want. Is that what you are needing or am I totally missing the question?
NOTE:\
If this interactive one is new to you, there are a lot of hints I can send along to speed the learning curve as I do spend a lot of time in it and it's not at all obvious on some points!
Plumbing specific here:
https://www.winnebago.com/Files/File...m/Plumbing.htm
Electric here:
https://www.winnebago.com/Files/File...ram/Wiring.htm
One of the big complaints in the computer world is that they never stop changing things!!
Good luck as it is a trek to try to keep up!
