I found that fresh air works wonders. And the best way to do that is to have 2 or 3 roof vents with Maxx Air covers on them so you can leave all vents open even when stored.
Even in winter storage I keep all three roof vents open. Plenty of fresh air moving through the trailer and rain never blows in if you have the vent covers installed.

I keep all 3 roof vents and the dash vent open 24/7/365. I prefer the
AeroFlo vent cover, but it works exactly the same. I've had the RV for 6 years, next month.
