The trailer isn't going to breathe through the gelcoated fiberglass walls or the glazed windows, whether they're wrapped or not. It might absorb some more heat if the color scheme is darker, but that's about it.
If you do have a condensation problem in storage, there are standalone dehumidifiers that can be run, or just a heat source to raise the dew point and create some convection.
West Marine links, but probably cheaper most anywhere else:
