Melting caulk

I have noticed, now that it's getting hot, that every couple of weeks or so, my TT has goo around the windows. This is a white "melted wax" look and I have to scrape it off with my fingernail. I'm just sure this is the caulk around the windows, and wondered if anyone has had this happen and what did you do to resolve it? This is our second summer with something besides a pop-up, and I noticed it last year too, but not as much. Help or ideas, please?? Our trailer is uncovered on a gravel pad.

Puzzled by your description of "white melted wax-like goo" The sealant used to bed most windows is black butyl rubber. You might contact Forest River and see what they say about this oozing onto the windows.

Sounds like the roof run-off to me.

There are a couple different types of caulk ("putty tape") used by RV manufacturers for sealing around windows and trim. One is petroleum based with some sort of adders for color and consistency, the other is a butyl, is better but still has the adders for color, etc. - and still will ooze some. Most caulks that I've seen and used are a light tan, black or gray. As far as oozing out from the window and trim to trailer siding - not nice, but unfortunately, normal and can be removed with a wood paint stir stick with the bottom edge sharpened somewhat. The worst part with any of these caulks is that over time (years) the windows should be removed and the caulk replaced with new - and a reason that RV manufacturers have in most cases gone to a closed cell foam seal instead. But they eventually fail too.
