Winterizing - Open vents

I'm almost done winterizing and covering my Flagstaff Microlite 23LB for the first time. After a little research, I have a few questions:

1. Do people cover the open vents (furnace vent, fridge vent, hot water heater vent)? If so, what do you use? I've read that some people do but I can't figure out a good way to do it. Some say to use cardboard, tin foil, or plastic wrap but I'd prefer not to have to remove duct tape residue next year. Thoughts?

2. I'm using an ADCO cover and I've read that some people leave a window cracked to promote some air flow in the unit. Thoughts?

Thanks again!
  • No cover.
    No covering vents.
    Windows and fans closed.
    Cover over the A/Cs.
    Covers over the tires.
    1 Large Damp-rid inside just in case.

    Never had any issues with mice in MH or previous TT.
  • For fridge and water htr vents ,just open them and place some window screen over opening then shut vent covers. Trim excess. If you want ,tape screen over furnace opening.
  • No cover.
    No covering vents.
    Windows and vents closed.
    Do cover the tires with tarps.

    Just let the trailer rough it out in the snow and cold. Hasn't hurt it in 8 years.
  • JMO but duct tape residue is a minor consideration if it means stopping an intruder. Reflectix is a great product to use for sealing any of these potential rodent entry points ... I've done mine in previous years but one year overlooked the furnace vent and the following spring discovered a mouse (or mice) had made it into 2 of the 5 heating ducts in the trailer. The smell was AWFUL and the only way I could fix it was to replace the ducting. I suspect the mouse (or mice) climbed up the ADCO cover and made it's way into the duct by way of the furnace vent as there were absolutely no droppings or other signs he/she/they had made it into the trailer itself. When prepping the trailer for winter storage I close the vents, all windows, distribute Fresh Cab rodent control in the trailer, and put out a container of Dry-Z-Air and always find the trailer fresh & clean in the spring. :B

    3m makes several kinds of tapes.. I find the blue painter's tape removes easily with no residue. Of course it costs more.
  • I don't do either. I do put a container of moisture absorbing crystals in the rig to help with any humidity issues - not sure it's needed but it's inexpensive and seems collect alot of water.
