2020 class C Thor Outlaw roof

Hi,
I am wondering if the sealant should have gone to the edge on the back toward the sides as shown.
Also it appears beige is it beige Dicor sealant.

It looks like it is not the factory original sealing. Is it possible that someone fixed a developing problem? If so then maybe the only part that needed fixing was the middle of the seam. This wouldn’t be unusual. I check my roof 3 or 4 times a year and more times than not have to address some issue. Usually I only address the suspect spot and won’t re-seal an entire seam. So it’ll only be a problem if the not beige parts near the side shows cracks or any other way for water to penetrate.

I agree: it looks like a bit of sea-sealing in order to stop a problem in it' tracks.

No I bought it brand new and it was built only a few Months before. It was a fresh one.

It could have been some quick repair work by the dealer...

Wouldn’t it be normal to seal the back seam. The area in question is the red circle where they didn’t get far enough to the edge. Everything is done in beige sealant by the way.

Here is a couple more pics. It is factory sealant.

Do yourself a favor.....

Clean the roof with a good cleaner and protector and then put EternaBond over every seam and joint where there is Dicor. Make sure you overlap it onto the roof itself as well.

You won’t have any leaks and you won’t be checking the roof and adding Dicor every 3 - 6 months.

If you have to replace something, the EternaBond will be hard to remove but I’ll take that over leaks.

Well I put Eternabond on many of the joints of my last toyhauler. However some things still had Dicor like the plumbing vents. There are other awkward areas that I still would need Dicor on the motorhome. So I’m not sure I want to Eternabond the brand new motorhome yet.
I took a picture of the top and it looks like they used a clear sealant on the rear side and the top of the side molding. Does anyone know is that Dicor ultimate sealant where you use the primer?
