Molding on 320

Otto

I'm a new happy owner of a 2021 320, and have a question about the black trim along the top of the trailer. A couple of questions:
1. Can the pieces be carefully screwed together? Previous owner did lose a segment while driving on the highway. It's been replaced, but I wonder about that possibly happening again.
2. Along the roof edge there is a little piece of rubber that is friction held onto the trim. I see that I'm missing that piece of rubber on one section. Where would I look for that replacement part? (assuming I need to replace it........)
Thank you so much!

Amazon has the molding with two day shipping.  I just use a little clear silicon in the groove, to keep it in place once slid over the plastic.

I also attached all my trim pieces together with 1" metal roofing screws with the rubber washer.  The top piece of trim, I drilled a hole almost the width of the washer (just a little smaller so it doesn't go through,) and then just a pilot hole in the trim piece the top piece laps over.  That allows the two pieces to expand and contract without cracking either one.

There are two kinds of trim on the trailers depending on the various model years.    One is thick ABS plastic.  The "newer" version is a lighter plastic type that is a bit different than the thicker ABS plastic.  If whole sections of your plastic has flown off, it "probably" it the thinner type.  This video shows one way to secure the "lighter" plastic to make sure the wind doesn't simply work its way under the plastic and drive it off.

So, it is important to sort out exactly what type of "trim" you have.

Here is an example of an owner of a 2016, with a "crack" in the thicker plastic trim.  A different design compared to the "newer" trim.

There is one other "distractor" when talking about the "trim".  There is a black "rubbery" sort of trim that lies along side the ABS trim, and this trim has a tendency to loosen up and need to be reglued.  It is a pretty common RV part. This is one of many of the "ABS" trim threads that discuss cracked trim, and it shows the trim that GBL posted in his thread above.
