What kind of roof do I hve?

[Flyer]

I have a couple of spots that could use some touch up sealant. Also between the camper and the gutter.

2020 GD 367BHS. MFG Date is early-mid 2019.

What lap sealant should I use?

I bought these from Amazon. The more I research, the more unsure I am.


Alpha

Dicor

Neither seem to specify TPO or not.

Looks like all info was in the owners manual.

**I forgot I could get that info from the MyGDRV site until I found the forum searching something else.

In case anyone else is looking for this specifically, Alpha sealants are noted in the owners manual. Specifically Alpha 1010.

That being said, I assume the Alpha sealant mentioned above would work. Can anyone confirm and / or explain the differences?

Alpha 1010 is non-sag which would be use on vertical areas or side edges of the roof. The 1021 is self leveling which would be used on flat surfaces, around skylights and such.
