One foolproof way to tell is run a screw out and look at the threaded part. If it's rusty, the issue is underneath.

Well, I peeled back the vinyl trim a bit, and water came out and the space was filled with slime. As the vinyl trim is old and loose, I'm pretty sure that's my problem.

But when I replace the vinyl, I'll pull out a couple of screws to be sure.

For peace of mind, I would if I were you. If the threads are fine, just remember to add dome sealant to the threads when putting them back in.

That screw is like a dipstick. If it's rusty, you have issue, if not, be happy.

Yes, think that's the "heavy duty" stuff I saw at Camping World.
Maybe it'll last a bit longer than the regular Camco trim?
Guess I'll give it a try.

Only that it is much easier to install if it's warm out and you let the vinyl lay in the sun first.
Good luck!
