Should I Throw In the Towel?

Your doing something wrong!
Either your doing very poor PDI when you first get your trailers.
Your not keeping up with regular maintenance. You are not being obesrvant enough to catch/discover small issues before they become major problems.
Your latest issue is an example. It is common for skylights to leak in all models however the leak does not have to lead to a totally soaked ceiling!
RV's are in constant flux. You must be observant and aware at all times as you use your RV.
Pay attention to all the liitle squeaks and noises. If it seams weird investigate further. Notice a wet spot, find out why? Hear an odd sound,find out why? It is an on going battle, but you can win. You just need to be diligant aware and observant.
As to your current problem unless you have the skills to DIY you are at the mercy of your dealer and manufacturer. Executing the warranty is full of pitfalls

Well fella, when you don’t know the reason why I’ve had trailer issues, you really shouldn’t assume (you know what that means) that everyone is ignorant and stupid in buying, operating, or maintaining their RV of trailer JUST because they have a history of more than one bad rig.

I didn't sign up for this rodeo last week or last year. Ive done more trailer repairs than most, and when I can’t reasonably take care of it under warranty or out of warranty, THEN I get a bit testy. You see, the first bad rig had the frame sag 4 inches in 8 feet off the rear a year after we bought it. Not quite a maintenance or PDI issue. The second trailer had the slide removed after the floor rotted out of it in the first year. The rubber roofing was not terminated under the flashing, and back then, no rain drip edges were on the exterior wall above the slide. When the pulled the slide out, they laid it on its exterior face and drug it across the shop floor gouging vertical scratches all the way up the wall face. THAT was 1/50th of the issues the FACTORY created during the warranty repairs. Now on the third, I just walked the roof two weeks before. No issues. In fact, we haven’t had rain in our area this spring or summer to measure in inches.

So, if I you find how any of these are maintenance or PDI issues, please, let me know. Do you walk the roof on your fiver daily or four times a week? I can’t imagine much change in a trailer in the typical two week span I walk the trailer and roof checking for leaks, caulk issues, or cracks… while it sits in the driveway. Now, after storms, or other possible damage creating events, I’d expect to be more diligent.
