Vent Cover Revisited--Now More Air Flow

It's hard to see an RV that doesn't have an after-market vent cover. When we say vent cover, we're not talking about that flat plastic (or metal) lid that covers that hole in your roof. Rather, these covers allow you to roll your roof vent open in nasty weather--keeping the rain out, but allowing an exchange of air.

The "household word" for vent covers for most RVers is Maxxair--they've been on the market for years. We broke down and bought a couple for our fifth wheel after years of cranking our vents open and close in a synchronized response to weather conditions. However, we weren't enthused with the way they crimped our air flow--having one on just didn't allow a real good flow of air.

Recently we had to pull vent covers off to perform vent lid maintenance. Don't forget a wrench before you make the roof ascent--the Maxxairs require tools to take off. Correction: They did require tools.

Maxxair has just hit the market with Maxxair II (is that "son of Maxxair?). Promising "Twice as much vent area as our original vent cove," this second generation offspring also promises to make maintenance issues a bit easier: Now you simply pull locking pins from one side of the installed vent, and the whole thing rolls over on the opposite side.

The extra ventilating power is provided by a larger vent-to-air ratio, and by providing cross ventilation through side louvers. The company also crows that the new covers can be used on powered ventilation fans, however one RVer noted that with the cover installed, he can't open his FantasticFan fully--but it still able to operate it successfully.

CampingWorld prices the son-o-Maxxair starting at a "member" price of $39. That's about ten more dollars than you'll pay for the original product.
