So, I figured I'd do my best to make lemonade out of my lemon and share the experience so perhaps you don't have to. Turns out anybody with one of these or any CAMPER that has the full four sided extruded aluminum trim around the slide out is likely to suffer a water leak condition.
We bought this 2019 at the start of 2020 - who knew 2020 would turn into what it did - and thus the camper only went out three times. I'm stickler for maintenance which is why this water leak really bit me bad.
While my dealer may have attempted a good will warranty request, I was JUST out of the one year warranty when I discovered it - and frankly for the couple hundred bucks and a few days work it was easier to knock it out than to haul it down and be at the mercy of them and likely have to pay a percent of it since it was just out (less than a month) of warranty.
Here is a WAY too long video of what I found...and a way to repair it - as well as hopefully prevent it for a LONG time.
If you have this type of slide out - check the seal/bond of the lower extruded trim as it rocks to and fro when open and close and they frankly don't seal it well from the factory.
