The exterior trim piece that covers the rear cap joint is separating from the fiberglass wall on the passenger side. Anyone know if there are clips or anything to hold that piece on. I'm not sure what I'll get into if I take the whole piece off and try to re-glue it. See attached pics.

I had the same problem on the driver's side of my 2018 MADP. Here is a link to the post discussing my disassembly and repair (along with pictures).

Just returned from Newmar today from having mine fixed. They replaced the strip. Now they use a two inch molding and is screwed and glued then painted. Also the wall was spongy so it was glued also. They said in my year coach they had problems with the adhesive that was used . everything seems to be right now. The other side showed signs of the same thing happening so they both got fixed! 2011 MADP

Thanks for the feed back. I’ll follow what Flyboy did. Maybe add a small screw or two. I dread having to make the micro caulking bead at the end.

A couple of things I learned in the process is slowly using a razor blade to avoid the paint coming off with the trim. The use of masking tape to define the borders of the new caulk bead. And the use of denatured alcohol to wipe down the bead without having the caulk stick to you finger. Always good to practice first.

So you taped off the trim edge on both sides leaving 1/8” or so, put the caulk bead in, and wiped it off with a rag with alcohol?
Did you remove the old caulk with a razor after removing the trim piece?
The 1/2 tape I ordered seems pretty thin to hold the trim long term. Did you use any additional adhesive?

Yes, but I used by finger, covered with denatured alcohol, to smooth out the bead. The same way I smooth out bead in the stick & brick kitchen and bathroom. The silicone caulk with become tacky relatively quickly, so you cannot do too much of an area at once. If you don’t want to use your finger, they make a caulk edging tool with different radius edges to get the desired bead thickness.

Yes, but you need to be very careful not to scratch the paint. Some have suggested using plastic putty knives.

No, no other adhesive. The trim isn’t very heavy, and you also have the silicone caulk holding the trim in place.
