Winterizing question.

We are seasonal campers and I am noticing other campers covering up the vents to the hot water heater, furnance and refrigerator with plastic garbage bags. Is this really necessary. I have always been under the impression that the more the camper breathes the better. What am I missing?

Covering those vents when closing up for the year can help prevent snow from blowing in and unwanted guests too. But I never have covered any of mine and no ill effects

Just ending the 7th year on our seasonal site and never covered the vents to the hot water heater, furnance or refrigerator. Never had a problem.

Sometimes covering those types of things up just makes it worse...if some humidity gets in behind the garbage bags,and inevitably some will, it never really dries up properly and can make things rust faster. The bags will tear a bit from wind or whatever and some rain or snow will find its way in there...then on a warmer sunny day it will sweat...The same goes for covering a/c units. Our son in law is in the a/c business and has always told us best to leave it exposed so humidity doesn't get trapped under the cover, then just give it a good rinse with a garden hose in the spring...thats what we have done for years now.

I asked a fellow camper why he was covering vents with plastic and I was told it was to prevent spiders from making nests in propane burner tubes. I know that a spider nest can stop a propane device from starting but I don't think a plastic bag will stop a spider from getting into a water heater or fridge vent.
