I came across this Winnebago video that shows how the roof is installed (a little after minute 13)

It makes it a little more clear to me how it is done, and emphasizes the importance of keeping that seal in good shape. I also learned it is not a moisture issue, as if the seal leaks water only goes into an aluminum channel - the issue is simply keeping that rolled fiberglass in the channel and not let it pop out under any circumstance.
Not a great design, but manageable if you understand it. Here is the sealant number and type:
Sealant E is a Seam Sealer: Part Number
094401-04-000 is a solvent-based sealer, versus
a silicone or urethane. This product is milky
when applied and becomes translucent when
curing, allowing the underlying paint or gelcoated
fiberglass to show through.
The sealant depends on the finish. The sealant fallout sheet for mine (2005) shows sealant "A", a urethane for the roof edge, but if the area is painted then the above part number is recommended.
