If you are a guy that likes to know where they put what and how things fit together, there is a great site for the post 2010 RV here:
It's a combo of us folks who want to know and the new stuff we have to figure out how to make it work to see what we want.
Great stuff but tricky to learn to drive it?
But when it's cold and wet out and you have just got a new RV, it sure can tell you lots of things without you crawling around in the cold to find!
Winter's coming to my house today and if I had an RV to winterize, I would love to find the drains without working that hard to find them!
Get to the things you want like plumbing and then if you want to look closer at one item, click on the + sign in lower left and then on the part. That will keep that part centered as you scroll to zoom of drag the curser to turn it around.
The part you click on will turn yellow and pop up in the parts list at right.
If you find the part in the list at right, click it there and it lights yellow on the drawing.
Handy for things like an inverter you find in the list but want to know where they hid it?
