I just meant, any time a hole is cut into something and something is put in the hole (like a latch in this case), there is a chance there can be a leak. I don't have slam latches, but I would think there should be butyl tape/putty between the latch hardware and the door. Whenever I put a hole in the side of the camper, no matter what it is for, I use butyl tape under whatever is being screwed onto the side of the camper.

Removed the latches on both sides today. The metal parts inside are quite corroded as seen in the photo (in the 2 years we've owned the TT from new). The open-cell insulation is stained and wet to the touch. The latches are definitely leaking.
The outside piece has a thin closed cell gasket to seal against the door surface. The 4 attachment screws holding the inner and outer plastic pieces together were reasonably tight but I did cinch them up a bit more. I took the outer piece inside and filled the cup-shaped finger space with water and I didn't find any water getting through to the interior side so it must be the gasket that is leaking. Butyl tape may be the thing to use or perhaps some Proflex caulk? Maybe I should call Challenger Door, the manufacturer to see what they have to say.
Water intrusion into an RV is not a good thing and I need to fix this.
Seeing what these things are like inside, they're really not very secure. One smack with a hammer and you'd be in.

Anything can leak if not installed properly. Remove the latch; if the wood is rotted around the opening for the latch, you know that's the problem.

I think it is the piece in the door that might be at fault, not the striker plate if that's what you meant. The pull/handle part in the latches have a horizontal pin for the handle to pivot on and there does not appear to be anything to prevent water from getting through. The roof gutter has a downspout that dumps water dead center over the doors so if it is windy at the same time, I think water may be getting blown hard against/into the latch. We are on acreage with no trees and over the winter we get some very strong winds that will blow water from the downspouts against the compartment doors. We didn't put our cover on this past winter and may be why I didn't notice anything this time last year.
I'll take it apart to see how it works and if there's something wrong or if an improvement can be made. It might be that the downspout is just in the worst possible location and there's nothing that can be done? The downspouts are the extended type so can't get water dumping any farther away from the doors. I may try putting a paper towel on the floor of the pass-through and spray a hose against the latch to see if water gets through.
Our slam latch looks like in this photo. KZ started using them in our model year, 2014. There's a number of different slam latch manufacturers. Don't know if others are any better or what brand we have.
