Do you have electricity at your trailer?
There is a device called Dampp-Chaser that is used inside pianos to
keep them from soaking up humidity. *It is a long rod that is heated
electrically and will elevate temperature enough *to keep a piano dry
(but not *too dry). *Two or three of these strategically placed might

When my repair shop was open we would open all trailers regularly and
the metal trailers were always wet inside. The fiberglass tops
weren't, neither were the wood trailers. I believe the moisture came
from condensation and would build up inside to the point the ceiling
would be dripping water droplets over time. Recommend opening your
trailer as often as possible and installing a solar fan with a small
vent on the floor at the opposite end of the trailer so the fan can
change-out all the moist air during the day when the solar fan is
operating and the air isn't so damp. Left long enough and moisture
will build up inside the cockpit, ever notice rusty bolts in your
cockpit? I even saw one bird with moisture inside the instruments, but
the trailer hadn't been opened in years!
