Vent Covers

[Abnmarine]

I just installed two Maxi Vent II covers. One vent is in the kitchen and the other in the bathroom. Pretty easy install. My question is to those with covers, do you always leave your vents open in the summer? I know rain won't enter, just curious what you all do.

When the heat and ac is on, we close our vents. Otherwise we dont.

That's what I intend to do as well. I already could feel the air flowing and hope it helps cool it some when parked.

As the O/P said unless I am heating or A/C I have my vents wide open all the time. It keeps that all important air flow in the motor home to keep things dryer, and fresher. Even when I am using the heat or A/C, I have them cracked open a quarter inch or so.

I have my vents open any time I'm not running heat or air. Even all winter with the cover on, I feel it helps with circulation. John H...

Yes, vents can be opened when in motion on the road also ????

If you leave the vents open when driving - you can cause a negative pressure inside the coach. This can cause air to come up from the tanks - via the vent pipe and cause a sewer smell inside the coach.
I have even seen bubbling in a toilet that had water in it.

I have heard that before, but have never had it happen to me, but it is a good point and all should be aware. I think it can vary from coach to coach depending on vent location and whether or not there is make-up air somewhere else.

I leave my bathroom vent open about 3 inches when stored. I then leave the bathroom door open. My theory is that is will help circulate the air flow in the RV while sitting idle. I have yet to walk in and have any odor issues.
