Roof Sealant Gaps on 2604ws

I cleaned the roof with Dawn dish soap today - had noticed a lot of black streaks forming on the front and side of the trailer and deduced it was dirt washing off the roof. While up there, I noticed two things that concern me:

1. The awning on the large slide-out seems a bit loose, has a belly in it that catches a lot of dirt and water. How does one tighten up the awning so that water and dirt do not collect, but runs off one end or the other?

2. I've attached pictures of gaps in the sealant on the front edge of the roof. Do those openings continue into the front wall of the camper, where does water go that leaks into those cracks and should I worry? Should they be primed, then sealed with appropriate products?

Eternabond all seams on roof and you won't have to worry abour cracks in Dicor causing water damage for a long time.

The slide topper sags in the middle because the roller bends in the middle. Dirt and water collect in the sag making it worse. The roller probably could use a support in the center, but I don't know how it might damage the topper over time.

Ditto to the eternabond. We picked up out new Puma last Thursday and although some may say wait till the warranty is up I went up there last night, cleaned the roof and put down eternabond around the one roof vent, skylight, fridge vent, the full front seam and the back seam. I'm not taking chances. After that I put down dťcor SL sealant on the seams of the eternabond. Nothing is getting past!

Good advice on the roof seams so I won't add.

On the slide topper... remember that most topper awning manufacturers don't roll the awning springs as tightly as the main awning. Reason being, so that the tension of the roller/topper doesn't interfere with the slide operation.

Consequently, (because of the lesser tension) they often sag and hold water.
But that isn't really a bad thing.

The water and dirt/debris is sitting on the awning rather than your slide top and when you close the slide, it rolls off. Other than you 'might' get a bath if standing near the slide when retracted, Id rather that water/debris to be on the topper than my slide roof.
