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.

I agree with Larry. I have had a trouble spot on the front of my trailer for years where it constantly split over temperature changes not matter what I used. Just re-caulked with 3M UV4000 and no splitting yet after 4 months and going from 70F to 5F here in Canada. Proflex would split after going from 70F to 55F. More money but so far seems far superior.
