Right. This is what I do. It need not run much to keep things

A positive side of trailer vents is that whatever the temperature =

Yes. Certainly a dehumidifier is not appropriate for all situations.
Use judgement. When the wet weather comes, if you live in an area
where it becomes wet for days and weeks at a time, the dehumidifier has
worked great for me. Even when not so wet one can avoid the daily dew
cycle...
