If you get the small ones you will either spend all your time emptying it or leave it turned off - I would personally get the bigger one. When in FL ours runs 24 hours a day unless we have a "dry" spell for some reason. Makes a huge difference in condensation - we have none.

Looks like your trailer is right at 31'. IMO I would go with a nice 30 pint - should cover the bases no matter where you are. I bought mine at Lowes. From what I can tell I wouldn't spend less than 150 or so; we paid about that around 4 years ago for ours, and it works like a champ. You want it to be efficient and effective. JMO/YMMV

Ours has auto off when full, and you can select the humidity level you want, we stay in the 40% to 45% range. This way you don't need vents and windows open when it is cold and humid out side.
