When new and finding your way around the new RV, there are almost always questions about where to find a part or sometimes you find a part and wonder what it might be.
Winnebago does a really good job of putting some helpful info online if we know where to look.
This is my fav for finding things as it is an interactive site where we can turn the Rv all sorts of ways and "look through walls" to find or ID things as we go. It does have a leaning curve of it's own but can get to be a real help once learned and after playing with it for some time:
Plumbing is often an item to wonder about when we get into how things might work, or for sure when they don't!
Wiring can help to find the breakers, if it comes around to that:
Not saying you will ever need all that info but really good to have just in case?
Good luck to you and enjoy the learning curve!
