Front Cap Sealant

[Aneff]

Cleaning the roof and notice the caulking around the front cap and the gutters is cracked (see pictures). I have a 2013 Vista 35B. Should I remove all of the caulking and start over? If so, what type of caulking would you recommend? This would take a loong time! Any thoughts?

I'd remove all you can without doing any damage
and re-caulk with GE 100% Silicone II
Should last 50years. Be sure to get the II version of
the GE silicone. It has better adhesion and longer life.
There will be lots of opinions on the issue of caulk.

I'm not sure silicon is the way to go. I'd go with what Winnebago recommends.

Here is a link to the sealants used on the Vista 35b:

If you want to try an aftermarket product, you can probably input Winnebago's part number into a search and probably get a few hits on caulks that are comparable.
