Best caulk for RV's

What brand do most RV owners use to caulk the seals on the exterior of their rigs?

I'm a rogue and partial to the more robust 3M brand Marine adhesives/sealants especially the UV4000. I redid my entire trailer where it still required caulking with the 3M UV4000 almost 8 years ago and it still looks as good and pristine as when I originally applied it.
