What kind of caulking?

Just don't use silicone based products as they cannot be easily touched up in the future.
I am an overkill guy - use 3M 4000 UV marine sealant on roof and sidewall applications. It is not self-leveling on the roof like one version of Dicor.

Can you get Dicor or Proseal at any auto parts store or is it a online purchase? I dont have a RV store anywhere near me.

It happens with age.

Also check for sagging in some parts (another sign of age).

I like Dicor self leveling on the roof and Proseal on verticle surfaces.

Let google be your friend as their are several sealing products out here for keeping a RV water tight. Some even come with a how to do it you tube.

Was thinking about rubbing the dark caulk out and replacing it with white.

Lap seal for the roof and the other one for all else.

Thanks! The roof looks good just have to touch up a couple of the seams on the sides.
