Well another weekend in the RV, and another problem.
After sitting through a deluge for a few days, when I was packing up the RV I found some moisture. I had noticed the moisture damage before but thought it was from the original owner as I never found moisture there, even after rain. This weekend we were stuck in the rain all weekend and it was pretty evident.
This also explains why I can't get that plastic strip to stick either.
Here is the moisture:
So I went up on the roof and could not find any obvious area where it would be leaking. So I started pressing on the sealant and it looks like it is cracking? For the time being I just put some packing tape over it to try and keep water from seeping in there, but could this be the problem? How do I fix? Can I just buy some more sealer and goop it on there? Or do I need to start stripping it down (that seems like a lot of work and I hate heights lol).
Here are some cracks:
