Sealing 5th wheel exterior

I have a 1985 alpenlite 25ft 5th wheel. Some of the sealant around the joints and storage compartments has seen better days. Using information on this site it seems to be a bad idea to use silicone. That being said I have seen dicor and proflex recommended. Two questions my unit has a aluminum roof with a fiberglass front cap. Those products talk about use on rubber roofs. And can these be used to seal around joints and compartments on the sides of the unit.

Thanks in advance.

Silicone is fine to use on the sides of a trailer. Proflex is ok, but if you're going that route I like Sikaflex 221 better than proflex.
For the roof, Dicor will work on those materials, as will Sikaflex 715, which I prefer.

There is self leveling lap sealant. You don't use that one sides because it will run.
There is NON self leveling that you can use on sides.

My Alpenlite (1994) used silicon on the window and compartment seal edges. When it got old, I removed the excess with a razor blade and reapplied silicon sparingly. On the roof, I would use Endurabond. Sticks to all surfaces except silicon. Never use silicon on the roof. There is an Alpenlite travel club on face book with owners of older Alpys like yours.
