I'm still working like mad on my TL, taking care of manufacturing shortcomings and 7 years of deferred maintenance.
I have started cleaning and inspecting the caulking used at the seams to see where I have to touch it up or re-do it. I did find one thing that you all should be aware of. They used something like this on all the body seams and protrusions, except the roof:

Maybe they used that exact product, even.
Well the problem is that they used it on the two seams where the TPO roof meets the upper side molding. According to the description at the product page, it doesn't adhere to EDPM but it doesn't mention TPO. Mine is not adhering.
How do I know what they used? Well, it looks and feels exactly like what is on my Crossroads trailer, and the Crossroads service manager told me that is what it is. In any event, whatever they used is not adhering to the roof at those two seams. It looks like it is, but it isn't. It is simply cured up against the roof membrane. If you stick a fingernail behind it, you will see for yourself.
What should be used is something like this, in the non-sag version
From what I have read at the Geocel and Dicor sites, I think I have to remove the old stuff before putting down the right stuff. Since it is not stuck to the roof, the problem is the opposite edge where it is really stuck to the aluminum. I've fought caulk removal before. It's not fun but it can be done without damaging anything if I'm careful.
Just something to look into. YMMV!
