Trim falling off

I own a 2018 Chateau 24F, (bought in 2017, used). Trim is falling off on both sides of the coach. It's a simple trim that slides into a track. With heat, and cold it seems to expand or contract. I had to secure it with duct tape while we traveled back from Utah. Suggestions on how to repair/replace.

I had similar issues with a similar piece of trim on our old 5th wheel. I just kept an eye on it and pushed it back in after every drive. Yeah not the solution you're looking for.

Could you try getting some epoxy down into that tract, and then pushing it back down into place?

That's what I've been doing now for two years.

I was considering epoxy, but i got the sense it needs to expand/contract, and if glued down and have not flex, it may buckle somewhere else. Too much to epoxy the whole run.

I'm now thinking about cutting the trim material near the bend, so that it can expand and contract as it wants, and staying in the track. Overlap the cut trim area with additional trim, so that if a gap develops it will be covered up. Might work?

That's crappy. It looks like cheap peel-and-stick vinyl. You might get it stuck back down with 3M VHB exterior mounting tape

We had the same thing happen to ours, I got it replaced while getting some other warranty work done. But since it all came out on the freeway I ended up putting some guerilla glue on it and that seemed work.

That's exactly what happened to us. It was flying in the air on the freeway, the entire 12 ft. strip, unable to get it all back in place. Had it duct taped for the rest of the trip. UGH!

Thanks for the suggestion of Guerilla Glueing it. I will try that next.

I've been using this rubber/vinyl glue for medium duty repairs with good success. I would cut the trim at either end of the run. Get it positioned where you want it, then use dabs of glue to hold in place. I would NOT USE EPOXY! That sets up hard.

I stand cheerfully corrected, and hope that nobody followed my advice!

I had this same problem on my old class c. I took a heat gun set on low and warmed the trim to get it back in the track. Then I inserted a couple of small self-tapping screws. One on the vertical part of the trim about an inch below the curve and one on the horizontal part about an inch from the curve. Took maybe 10 minutes and lasted for years till we bought our next RV.

The whole length of ours came out on the 15 freeway right in the center of Salt Lake not an easy place to pull and fix. Once I put the glue on it made it down to Disney and then all the way back to Washington state.

All fantastic suggestions! I will try one of these solutions (guerrilla glue) and report back results.

Ours popped out the first year out. First the passenger side- held with tape till we could fix. Then the drivers side- on the highway! Pulled off and again secured with tape.
Pushed back in and used dot of gorilla super glue. Haven't had the problem since.

Had this problem on a previous C Class. Still under warranty so we put it on the list of issues. They heated it and put back in. A month or so later it came back out. They used dabs of super glue as suggested elsewhere on this thread and no more issues.

Like others who have replied to this thread, we have experienced the same issue.
The cause of the problem appears to be thermal. Meaning a change in temperature causes the trim to contract or expand. Since both ends of the trim are attached with screws, contraction can, and does cause the trim to pop out of the track.
IMHO, gluing the trim in place will not solve the issue. It’ll just pop out in another place.
I found a roll of replacement trim on Amazon.com and plan to replace mine in the spring. I will make sure there is sufficient slack in it before I attach the ends.
My temporary fix was to cut the trim in the middle and put it back in the track. It leaves a small gap but unless you are looking for it, it is not that noticeable.
Just my two cents worth.

You are correct when you stated that the condition is caused by temperature. This condition can can be corrected by removing the rubber strip and pulling it to stretch it. This will put more tension on it and keep it in the tracks. No need to put messy glue or tape to hold it in. When you do your periodic walk around , you may need to pull it out and stretch it again. Not a cure all but an easy fix.

Normal for Thor. I just put some epoxy in track

Same thing on our 2018 Freedom Elite 24FE and I just used some clear silicon sealant to hold it in place. It keeps the trim in place, flexible to handle expansion and contraction with the temperature, and can be removed easy enough if I ever need to remove the trim for some reason.
