I am not near the trailer right now (off site storage), but I don't believe is a side to side issue. I can pull the bar inward enough to snug the window, but then I am about 3/4" too far in to latch the bar. I can push back a bit and latch, but then the window is about 3/4" open and I know next trip down the road the wind will catch it and force open again.
I have to confess that I keep the trailer stored in a storage unit and it has low lighting, but when I looked initially.....something is wrong and I am too dumb to see it right off. Could be something very simple, I just don't see it.
Thanks for the response.
