Are you shopping or just trying to get to know what you have?
there is a great tool for looking at all the newer model RV from Winnebago here:
https://catalog3d.winnebagoind.com/menu/Parts.htm
It takes a bit of "learning curve" to move around but once you get used to it, I find it great for pre-shopping as I can look for lots of those little hidden things without having to drive over to see!
If you already have the RV, it can be handy to look for things like those drain valves. Sometimes the manual is not as clear as they think, so I like a picture to add to the info! One way to spot a drain is to look for a tube sticking out the bottom and the valve is usually just above.
But I like looking at a drawing over crawling around under the RV!!
Enjoy the new trek as it takes time!
