my drivers side exterior, up towards the awnings, between the slides, there is a trim strip about 5" wide. The front few feet have come disconnected from the railing that it clips into.
I've been unable to clip it back in, I think part of the problem is that the plastic is just too old and rigid. I've tried spraying silicon lubricant on the rail and plastic both.
I've tried sliding the trim out as far as I can get it, hoping to reengage the lip, but I can't slide it out far enough.

Anyone ever deal with this trim strip issue?
