High quality 100% pure silicone will do fine on the sides of trailers and openings.
Silicone will not do as well as Proflex though. Silcone many times tends to peel or raise around it's edges. Proflex does not tend to do this. Proflex is very difficult to remove once cured; as silcone is usually much easier. I also don't recall seeing Proflex subjected to mold as quickly as silicone.
Silicone on EPDM or TPO will not hold up. (nor is Proflex recommended) The silicone will appear cured and dry, but it will peel right off showing that it never fully cures to that surface. Larger amounts will still be soft just as it came out of the tube.
Silicone on sides: ok and cheap cost
Proflex on sides: expensive, but more permanent, it also shows better long term, and I believe it tools better when applying.
+1 for Proflex
