Should Maxxair vent covers be closed when traveling?

[markb422]

After a long haul with the bathroom vent open there was dust and road grit on the br floor and on top of the toilet seat on arrival. Not much to clean.

DON'T Leave vents open when driving on gravel or dirt roads! The Maxxair vents create a suction and fine silty dirt will invade your trailer through the smallest of holes! How do I know this?😳

I can only speak for myself on this but I camp on top of a good size hill and we always have a breeze blowing, When the a/c unit is running we do close the vent, the air blows the warmer air into the camper unless we run the fan. I have the fan on the thermostat, when the temp drops below the set point and the fan stops the lid gets closed. Other that that it's open 24/7 parked or rolling!

That works to a point, but the AC will pull some outside air in from the vents. Much worse with 90+ degrees and really humid. Took me awhile on the last trailer to figure out why I wasn't cooling down.

I've found recently that running with both vents open and one fan running while traveling speeds things up well. Shut the vents and turn the ac on when I get there.

I agree. My practice is not a matter of physics but experience. I forgot to close my single vent. It's in the bathroom which has no A/C vent. The rest of the trailer cooled off BUT when I went into the bathroom, it was stiflingly hot. I closed the vent and the bathroom cooled off post haste.

I think the reason we install covers is so we can leave them open !!!

Emphasis on having them installed properly...ie...screen facing the rear of trailer! Would seem to be common sense but this summer I saw a guy going down the highway and he had his the wrong way...was facing front of trlr...in his case any rain would get driven in! I would even think there could be a risk of that cover getting torn off just with the head wind getting into it....Not so common sense to everyone I guess!

Hard to believe the actuall crank up vent is installed facing forward.

The thread is about vent covers. I believe someone installed a cover backwards... not the vent lid itself.
