My air condition will sometimes freeze up in the middle of the night when it is a high humid night.
I also get inside condensation off of metal things at times as well... Not fun waking up with water dripping on your nose from the metal tent support going over your head haha... Running a O2COOL 10-inch AC/DC fan inside the trailer all the time really helps us out for the condensation problem. Of course we are a tent trailer and these problems are very common for tent trailers.
We take it all in pride - it goes with camping
