Ok, sitting here at Yellowstone today during a major thunderstorm. Noticed water coming in from the bottom of frame area for one of the rear frameless windows. Sat on the couch during the storm with a towel trying to catch the water as it came in. I've got some clear weatherstrip tape that I'll try to put on the outside top edge of the window (as soon as I track down a ladder that'll reach). I really don't see anything wrong with the window, so hoping it's nothing major, trailers only 5 months old.....
This will be the 3rd item for the upcoming warranty work (leaking window, shower door screwed up, broken dinette chair).
Attached picture shows my wife pointing to right where the water was coming in from.
