Keeping roof vents closed

Super8mm · 07-09-2017, 08:00 AM

Yesterday. On a 420 mile leg of my trip both of my roof crank up vents opened up all the way

Is there something I can do to keep them closed?

Thanks

Yes,balance tires,put on MaxxAir Covers,tighten the clamp down pressure!

Youroo!!

Thanks

Tires are balanced. Or were before I put the tpms. Sensors on

I will have to see how tall the Max Air are as the specs say I am at 13 ft 2 in

We've had Maxxair covers on all every cover but one. We've had a TT, two fifth wheels and now a motor home. One 5th wheel we had a needed 4, I put three on.

The unprotected roof vent broken down from UV rays. The covered three were like new. I got to add that 4th one and a new vent lid.

I think they're about 9 to 10" installed. Can't be more than the A/C I wouldn't think.

good luck

Maxxair:

Maxxair II:

I have maxxair II's on all my vents. I like to leave the vents full open when driving under the Maxxair II's so it's cool and fresh inside the trailer when we pull up. They're a great addition, can leave the vents wide open even in driving rain.

X2. We leave ours upen all the time. No rain and the air is circulated as we drive. Our ac shroud sticks up higher. For the record we have the camco covers and love them. I would suggest an accurate measurement using a stepladder and a simple tape measure to gage the total height. You will have an actual number rather than one that could be totally off due to construction or even tire brand or inflation.

Had that happen on our previous trailer. After that I made sure vents were securely closed before travel. That cured the problem of vents opening but the covers eventually deteriorated from sun exposure. Installed Maxair covers on all of them and problem solved. Removed the Maxairs when we sold the trailer and installed them on the new fiver. As far as height goes they are lower than the air conditioner covers so clearance is not an issue with them. You can travel with the vents open to help cool the trailer.

We just bought a Maxair cover but haven't installed it yet. There is the option to have an additional screw into the roof of the RV on each side. Should I use it or just attach to the fan?

I just attached mine to the existing vent frame using 4 screws. Don't think I want to put a hole in the roof.

I don't think you read the Install Directions Correctly! I have NEVER seen MaxxAir say to drill into the Roof!

Youroo!!

We had a roof vent on our cargo trailer that came open on the road. Like yours. we always balanced the tires. Vents open are good, but not when you can't get to it. So we added a vent cover. Works great!

Ditto....that's why many people prefer the Maxxair over the Fantastic Vent...no drilling into roof...just onto fan housing.

You don't drill anything into the roof, just the vent housing. The brackets get bolted to the vent housing, the cover gets bolted to the vents (or hinged to the brackets int eh case of the Maxxair II).

From the factory, we have one vent with MaxxAir (front), one without (rear, over bathroom fan vent). FYI, just yesterday in Black Hills park we left the MaxxAir vent open slightly (maybe 2-3") while gone for the day. Per our usual practice, closed the front vent just in case. Wild thunderstorm passed through (dumped SNOW a few miles up the road!) and we had some spray come in through the vent. Nothing major, but a cautionary tale.

The way I read this you let the wrong Vent Open!

Youroo!!

DustyRoads · 07-09-2017, 07:07 PM

Use Maxair II vents unless you have a Fantastic Fan. If you for then buy their vent cover. They use the existing holes from vent.

jackconn · 07-09-2017, 07:15 PM

HA!! Good catch, Youroo....I got it backwards. The MaxxAir vent is in the back, which we left open a bit, and the other vent is in the front, which we left closed.

The Newsoms · 07-09-2017, 07:49 PM

My question is answered as I gather no one adds the additional screw but:
"STEP 12- You may wish to use the Optional #6 x 3/4" long screw to secure the brackets to the RV roof for greater stability..."
It's also shown in the YouTube video. If none of you guys did it, that's good enough for me.😁

Super8mm · 07-10-2017, 08:26 AM

Thanks guys, I will get it measured when I get home. I will find a nice level parking lot and measure roof to ground then top of AC to roof, that way I will know for sure with my truck

When we bought our trailer the manual roof vent cover in the bedroom would lift in transit. I thought we had a unique problem but I guess not!

The bathroom already had a fan, but we replaced the bedroom crank with a Fan-Tastic Vent. Both fans got the Fan-Tastic covers.

I consider the covers to be the first line of defense against UV radiation; they protect the vent covers themselves. These are designed to work with the Fan-Tastic vents and replacement is as easy as pulling four clips.
