Trailer Storage Humidity Control

[elmafarm]

I just returned from my first trip in a 16' Jay Feather Ultra Light. I had to re-winterize it because we are still freezing here in Buffalo, NY. The trailer will sit for at least one month. I plan to park it near my barn and plug it in to AC to charge the battery. How can I prevent it from getting that musty odor inside. Should I crack the roof vent? High winds, swirling snow and awful weather are common here.
Thanks for any ideas.

I keep my vents open a little to allow the humidity & temperature to equalize. Less apt to have collect moisture inside the trailer.

Wally World sells an odor absorber in the RV accessories section. Might also try a few boxes of baking soda around various places in the TT.

An inexpensive way is to go and buy a box of dryer sheets that you like the smell of and place them in every drawer/cupboard on board. I even place them in the beds. I do this every year as part of my winterizing routine and it works great.
