Did you have two leaks or was all of this becuase of the air conditioner heavy condensation.
On really bad humid days my air coditoner did the same thing... Trailer are not sealed enough to prevent the condensation on very humid days/nights I guess...
My air conditioner was roof mounted and we always dropped the back side of the trailer a inch or so more so water would run off the back more verses dumping into the patio area...
I never got wall damage out of any of this however...
I would think POPUP type trailers would be more prone to heavy condensation that a TT trailer would be due to the POPUP trailer canvas walls...
Be interesting to hear what CW says about it...
