Default 04' Cobra metal top leaks

How does the water sealing system on a Cobra normally work?

On the inside lower edge of each side there is a small trough. (A great place to store the TE probe, etc.)

If I look closely, there are small high water marks in there. Also drain holes at the front and rear ends. (One of which was clogged.) From experiments with a hose outside, it looks like a little water is getting by the rubber trim piece/rub rail on the outside. Looks like a possible design was if water goes out faster than it goes in, all is well.

Except there was a bit of carpet dipping down in the trough which wicked water up and over the side to the glider. So I'm wondering if anybody here has looked at how the seal system around the lower sides of the trailer top are supposed to be.

I may have to rethink where the nice shiny TE probe is stored as well.

Yes, condensation my first thought.
Drains clear is second.
Yes, quite a few threads on here for replacing clam to base seals.

Not to be a butthead (but I will be), search on replacing clam to base seals.
Cheap, search.
More expensive but easier, go to OEM support.

Thanks guys. Sounds like the trough+drains might be part of the plan for condensation, but that's not the source I'm seeing.

Also, the clam to bottom seal looks good and the leak is above it.

I'm seeing water in the trough from a hose streaming water down the side of the trailer over the rub rail. Not sure if this part is supposed to leak or not.

I can try Cobra, but I though I'd ask here first.
