Anything wrong with using a good grade of outdoor caulk (silicone) on the seams of my class C. Planning on replacing along the trim on the cabover. The stuff that is on there seems to peel off easy so going to remove it and using clear silicone to replace it. The stuff on the roof apears to be a vulcome caulk and that is in good shape. Just the sides could use some attention. Thanks for any info you can provide.

A quality urethane or polyurethane based caulk rated for the materials on an rv is best. There are some of these at the orange or blue box stores but ProFlex is a better choice. I use 3M 4000UV on my trailer -it is not cheap but rarely needs touch up in the same place twice.
Cheap silicone or latex based products will be "gifts that keep on giving" the first time you need to touch up a crack or void that appears.
Silicone based sealants do not adhere well to plastics or fiberglass. I use ProFlex RV lap sealant on the vertical areas and Dicor self leveling sealant on the roof seams.
