Sorry, not one that we have had but perhaps I can point you to some online info to look over some fine points before buying?
Things the brocures skip over!
The Winn home site as first stop for much online info if you've not found it!
https://www.winnebago.com/
Owners tab near top right, bring s alist of lots of indepth info. Everything from plumbing or electrical drawings to an interactive parts catalog. You likely do not want to buy parts but this set up will let you not only look at pictures of the rv from most any angle and any part like plumbing but also has a list that tells what sixe and shape all the tanks and where they fit! Where are the drains, where is the fill port, etc. for about every item on the RV. Also a floorplan!

My favorite tool to play!
Enjoy the shopping!
