Otherwise, as you drive down the road, air pressure will be reverse and push air into the vent, which will cause stink inside.
These improved vents are being OEM'ed for many of the better brands of RVs. But they cost $35 or so, vs $0.99 for the cheap vents Thor uses. |
Our 2008 only had a standard roof vent and only on very rare occasions would we notice a smell. We don't have any cheater vents under the sinks. My parents new axis has the cheater vents, both were defective and stunk. They replaced them and they only lasted a short time, it seems since the spring is so weak to begin with they don't hold up well to going down the road. They're now capped and no odor or problems. I installed a rotating sewer vent cap on the roof a few years ago and haven't noticed a sewer smell since.
