A plug for Maxxair II -- it works in a blizzard

(Dear Moderator -- I hope this is the right forum for this comment -- it is an evaluation of a do it yourself project, so that is why I put it here. Please feel free to move it if it is in the wrong place.)

About a year ago, I installed a Maxxair II over my bathroom vent because I was tired of hearing the vent flapping in the wind when we were camping. The installation was not technically difficult, although it was awkward to stand on a long ladder and work on the roof of the trailer.

Lasst week, we put the vent cover to the test -- we were camped in the Eastern Sierra, knowing that a snowstorm was on the way. For ventilation, we had to keep the bathroom vent open a little. The snowstorm turned into a minor blizzard -- very strong winds and about six inches of snow, with much deeper drifts.

The vent did not flap. The snow did not come in. The Maxxair did not get clogged with snow because of the design of the louvers. We had enough air, without gusts of wind coming into the trailer. Bottom line -- a happy camper.

I am not associated with Maxxair. But if you plan to camp in the rain or the snow or the wind, this vent cover does the job.

    Installed 2 of the Maxaair IIs a few months ago and it's one of the best mods I've done in a long time. Also glad I went with the II's over the original Maxaair.
  • We just installed two on our trailer yesterday. Pretty easy and quick too.

    Good to know! We have had them on our TTs for the last 6 years and loved being able to leave the vents open all camping season, without worry about rain getting in. I wasn't sure about snow, though, over the winter, so would close them then. I may not worry about it quite so much now! :)


    I used to live on the IL/WI border and those lake effect blizzards where the snow is straight line....a very small amount does get in. Not into the maxxair turbo fan cover, the plain vent cover.

  • I'm a big fan of them also.

    I installed 3 of them on my MH. 2 plain vent covers and one turbo maxxair with the fan on the outside. I never close them.

    They have been thru one big bad winter up North AND 2 tornadoes passing by the CG's I was parked in and no water or snow inside.

    2 thumbs up for me too.
