I have had form time to time some moisture in mine...not a vegas but likely similar construction
mine has the quarter turn locks and thumb latches.
I had my daughter climb in one of the larger compartments with a flashlight while I hosed it and she found that it leaks through the latches.... through the actual bearing or mechanism itself, not from the outer "gasket". they are not weatherproof latches.
I don't find that it happens very often so I open them up when I can to let things air out. so far ok
I have the slam shut latches on my Challenger and this trip I had rain get in between the layers of the outdoor kitchen door. Found the problem when I opened the kitchen and had water run over my head and back. I assumed (can be a bad thing to do) that the rain was getting in around the outside seal (if there is one) for the latch but now I'll have to look at the entire latch itself. This only happened when we got some driving rain that could be measured in buckets per hour rather than inches per hour. I also had rain get into the storage compartment in front of the outdoor kitchen. That looks like the rain got past the interior seal and that storage compartment is the only one with a drain plug installed.
Two additional items on the "To Do" list when we get back home this weekend. I believe I'll also order drain plugs for installation in all of the other compartments.

Hmmm, Shouldn't need drains in the compartments, who wants wet contents? Its not that difficult to keep water out of those compartments, unless you are submerged. Weather and water resistant compartments that stay dry have been built for years, and these can and should be fixable!
Challenger with slam latches. So far I have resolved ALL leaks by properly sealing the gasket joint. The rubber seal has a joint. Not sure why but on some of our doors the seam adhesive failed or was broken during installation. Water ran down the outside of the gasket as it should, until it reached the joint were it ran inside the gasket to the bottom. There are small holes in the gasket to release air when the gasket compresses during closing. Water built up inside the gasket and eventually runs out the holes and into the compartment. I solved all leaks by sealing the joint with some liquid rubber used to seal electrical connection. Available at Home Depot electrical dept.
