Hey All,Occasionally when on the road I see folks traveling with the roof vents open on their trailers. Made me think now that summer's here, does it really help keep the coach cooler when on the road?Just curious how many of ya'll travel with the vents open and if it helps?Thanks!

JMO, but I would not purposely tow at highway speeds with roof vent lids open, unless having covers over the vent lids. I think in some cases, people do not get their lids closed tight enough, and the wind turbulence on the roof works them open.Jerry

Yeah this happened to me on another trailer. Wind buffeting at highway speeds worked one about 4" open that I had cracked open a bit. We stopped in the rain which got every thing in the living room wet. Installed vent covers and no more issues like that.

We have vent covers on ours so they are well protected. If not I would have them closed. Sometimes I have them open but never in dusty areas

We keep ours open just a bit. The 'Venturi' effect from the small opening promotes are flow.

I tow with mine open all the time.Even if you don't have the covers it's not going to hurt a darn thing.

Years ago all vent covers were made from aluminum as my old '84 Aljo 5th wheel trailer was. They really radiated heat from the sun.
The covers stayed attached but leaving them up for a few trips stripped the drive mechanism.

Better vent covers than vent lids.

I'll dispute that! 2nd or 3rd trip out with my old Komfort, I forgot to close the bath and living room vents. Both were destroyed. Couldn't find the correct lids so ended up having to replace both the lid =and= the crank on both. Ever since, I have all vents buttoned up.

Uncovered vent lids will get brittle with age and exposure to the sun. Once brittle it doesn't take much for them to be destroyed.

I think there are different grades of lids.

I have a vent cover and mine only get closed a few times a year. If it's super cold (for a southern Californian that is)I'll close the vent at night to help keep heat in. Otherwise the vent is always open including towing down the highway.

I've traveled with them open before (with vent covers). By themselves, just leaving them open doesn't do much good when traveling in the FL heat. But turn on the MaxxAir fan and open them...makes a noticeable difference.

To be more specific they should be open all the way. Turning g knob Th snug it up.

I do prefer covers

They were. Both basically folded in half around the lift arm before they cracked the lift track out of them. About $100 to fix, IIRC. Pissed me off to no end as the salesman, who was also a friend, specifically warned me about not traveling with them open.
