Winnebago has had trouble with leaks developing in the bunk area over the cab, so they developed the one-piece fiberglass cap that they mold onto the Minnie Winnies, but sadly not the Outlooks (see photo below.) So, anything that cap covers on a Minnie Winnie could be a source of the leak on your Outlook.
I recommend that you clean the potential leaking area(s) first with rubbing alcohol, and then use the sealants called-out by Winnebago
, so as to maintain proper bonding with the existing sealants.
