caulk for corners

[thojre]

Hi. In with family working on remodeling our 1996 Wilderness, I'm in search of a recommended caulk for corners that will flex but not crack (too quickly, anyway) ... any suggestions? Many thanks

I use Dicor non sag for vertical and self leveling lap sealant for horizontal.

For RV corners, use a high-quality polyurethane sealant. Sikaflex 221 or ProFlex RV Flex are two good ones. They stay flexible for years. Clean the old caulk out completely before applying.
