We have a new 3575. Our trim [ 4' fin] on outside of bedroom slide is bent in toward body and seems to be getting worse. Did not catch on PDI. Purchased unit out of state. Started to notice on trip home. picked up trailer in April, went out for 2 week trip in June, upon picking up trailer from storage in July for trip i found upper 1/2 of my living room window on ground with inside glass shattered [ dual pane].when i was inspecting trailer for damage from window i also looked at bedroom slide and appears to be getting worse to the extent the caulking is cracking and two small chips from body where room and trim make connection. Is this common or a flaw in my unit.The other slide appear to be normal,My previous trailer all slide are same as day we purchased 6 years ago and it was half the price of the Bighorn. I do love the Bighorn, but very disappointed in the quality from a near top of the line unit.
