Thank you both for responding. This morning we had big rainstorm. At five, we were both standing in our pajamas, with flashlights, inside our freezing Caravel
. We were both surprised by the location of the leak. I really thought, as did the first responder, that it was coming from either the fresh water tank or the water lines located in that section of the trailer. My husband thought it was a roof leak. Turns out, it was actually more of what the second responder thought. On a '69 Caravel
there is pinstriping that is covering the point where the bottom pan of the airstream meets the sidewall. Part of this pinstripe has separated from the trailer wall and the water was leaking inside. It is amazing how much water can fit through such a small area! I later tested it with the hose to confirm. Anyway, thanks for your advice and caulk is on the way!
