Open or close roof vents for winter in snowy Colorado?

Our roof vents have the maxx vent covers and the ramble vent covers. We kept them open all summer with no problems with rain etc.

To keep air circulating I would love to keep them open all winter while the RV is in storage. Does anyone have experience doing this in a snowy climate? Any problems with this plan? Should I only keep them open an inch or so or is fully open OK? Or is it advised to shut them tight.

I would think fine blowing snow (which I am sure you get) could be a problem with vent open or closed. If it got in on the closed vent, where would the water go when it melted. No, I haven't experienced it, but I know fine blowing snow can get into just about everything.

IMHO you should be able to just ''crack'' your crank up vent. Turn it maybe half a turn where the ''vent cap'' is up enough to let air circulate but not up enough to actually let snow in without having to go ''up hill'' over the inside edge this of course with the understand that you do have ''Max Airs'' over the complete outfit. Also, it is assumed that you have everything that will freeze out of the coach and it winterized with anti freeze. It gets cold in Colorado..... (been there, done that)
With the ''vent cap'' just ''cracked'' it would give you circulation to keep the coach ''fresh'' inside.

Lots of luck and remember this advise is worth exactly what you are paying for it..... NOTHING....
Of course if it works well for you ,,,,,, you can give me ten cents the next time you see me so you wont look

Be safe and dont forget to THANK A VET FOR YOUR FREEDOM THIS NOV 11....

My mother owned a condo in a snowy region that had roof vents that were allowing wind blown snow to enter the vent and spot her ceiling.

The "fix" was to cut a piece of residential furnace filter slightly larger than the opening and wedging it into the opening ... no more snow blowing in the vent ... and it allowed air to flow both directions

Perhaps that would work for you too.

We left our vents open just slightly. I have maxxair covers on them. Yes, we did get some light snow blowing into them. One vent is in the bathroom and the other is in the cabover of our Class C. In our case, there was nothing that could be damaged by snow melt. If you are concerned about possible snow melt then the furnace filter (matted material type) would probably work for you.

Thanks for the replies!

Thanks for all the replies. We may try the furnace filters just to be safe. Not sure how I'll get my husband to get on the roof and put them in as he is for closing it up tight and I think the air circulation will be beneficial.

Thanks again!

Michelle, I too opt for the open vents. If you have the Maxair vents, you should be fine just cracking them open enough for air to move. They don't have to be open very much for air to move. I let ours open all winter, however ours has a cover on, so no worries.
