vent insulators

[Kyz]

In case anyone is wondering if those vent insulators help keep water out when you're a dummy and forget to close your vent lid... yes, yes they do. *facepalm*

(But it doesn't absorb the water, so be prepared to get wet when you remove it to close the vent lid.)

Thankfully the rain hasn't been that bad...yet...and that I finally noticed it after the 10th trip around the RV.

You mean the plastic cover is supposed to be removed?  

I thought it was like grandma’s couch with the heavy plastic cover to keep it from being stained! (Used). 

Those things really make the difference on a cold day. They keep the temperature from going way down.

I used to cover my vents with a layer of reflectix taped on the inside with gaffer's tape but warm moist air (Buddy htr) would condense and I'd get condensation in there till it dripped .
The Fantastic would be drenched arrrrgh
I leave 'em uncovered now, the condensation still happens but WAY WAY less,
Big Buddy can easily overpower the heat loss. Even on medium setting uptah camp @ -10* in a noreaster blizzard..BTDT and about to DIA.

They certainly don't get removed much! But occaisionally I like to increase the air flow on nice days. I hope to be more careful in the future!

No condensation, but I have temp gauges with humidity levels on them everywhere so I can take action if needed. Warm days the AC takes care of it; cool days, I have a dehumidfier that helps a bit. We have way more warm days than cold days thankfully.

I'm pretty dry with the electric heat right now but tomorrow back to propane BigBuddy....that's where most of it comes from , no water in here except for cooking.

If the vent pillows are inverted with the shiny side down, they will absorb moisture.

I flip mine shiny side up in the hot months to deflect heat, then shiny side down to reflect heat back inside during the cold months.

Going on 3 years now and never thought about doing that. Thanks Wayne.

You are welcome. Glad to be a positive contributor.

By the way, in an environment such as southern Nevada, depending on how much sunlight (UV) gets through the vent lid, the shiny stuff can decay to the point that when the insulator is removed, there will be a shower of glittery crud falling down.

Cheap vent lids, having had long term exposure to UV, can also become brittle, and collapse if a hand pushes on the lid, if one is off balance and ends up placing a hand on the lid.

Mine were brittle/cracking so I did replace them earlier this year.

Some posts just have that 'personal experience with this' ring to it...
