Breaks in Caulk

My trailer is the newer color - kinda light tan and chocolate. I have noticed several breaks/holes in some of the seams.

What type of caulk do I use, and it must come in clear because of the color of my trailer. (That's what's on there now.)

Is silicone a no-no? If so, why.
I looked for the Dicor, but it doesn't come in clear.
(Dicor is a urethane based caulk, as opposed to water based?)

Thanks.

    If you want to seal it correctly, use a polymer sealant like Proflex RV. If you already have silicone caulk failing in those joints, you'll need to remove it.

    Silicone will fail in a few years losing the bond to the surface it's applied. Nothing will stick to cured silicone, not even more silicone.

    I sent my dealer an email this morning questioning what to use on the gaps/holes I have found. This is his reply:

    Use Dow clear on the sides.
    Use Dicor on the roof. They make self leveling and non sag. Will need non sag near the edges.

    Google search of "Dow clear" has shown me it is silicone. So, you're saying Proflex won't work and I'll have to repair with silicone? :(

    Well, you guessed wrong.
    Jeesh.

    Where is the caulk, bathroom or outside?


    I was inspecting the outside.
