MaxAir II cover installation.

[shovelhead]

My neighbor is going to install my MaxAir II vent covers.  I cant navigate on the CL roof nor do I do ladders.  Should we place maybe some cardboard or thin plywood on the roof  to lessen him moving around up there?   The instructions look rather simple and I think a short time on the roof.  Anything  to watch for?

I was all over my roof today and it is very solid. Twas my first trip up there and I was impressed. However, to be safe, I did stay on my hands and knees the whole time in order to better spread out my weight.. @ 200lbs.

I've been on my roof a few times to see what's up there. It's very heavy aluminum, well supported by the rigid foam insulation underneath it. The first time I went up I used thin plywood, but quickly realized it isn't necessary. I'll be installing those vent covers on mine this spring too. The instructions do look simple. While he's up there, for sure have him look around at joints/seams/hardware/etc. to make sure all is well. If it's warm enough, have him give a coat of 303 Protectant to the plastic parts. It's great sunscreen for plastic.

I have also installed the Max Air vents. No problem working on the roof and I am over 200 big ones. Be careful coming down.

Do you have to cut into the trailer anywhere to install those?

[quote source="/post/7306/thread" author="@mitch" timestamp="1425128385"]Do you have to cut into the trailer anywhere to install those?  [/quote]I installed the camco brand.   I assume the maxxair install the same way.    If you look at the vents from the roof the vents are made with a lip around the opening about an and inch and a half tall to keep water from running in.   You have to drill 4 small holes in that vertical lip to install the vent, so yes there is drilling, but no not into the roof itself.   Some advertise themselves as "no drilling into the roof required" but in reality they all work the same way by drilling into the vertical lip.   


PS:  agree with the others about the strength of the roof to support a person, but being cautious when I installed mine I crawled and sat indian style to spread my weight as much as possible.

As TLB said only drilling is in the sides of the vent.   I went for the MaxAir II sense they claim they allow more airflow then version 1.
I also went with black to provide some sun blocking.  I get wide awaken in a lighted room and cant sleep.  I've read that some dont like the black because they dont allow light in....

Thanks

BTW, exactly which MaxAir II covers work for our vents?

[daplumbr]

From a quick re-look on Amazon, it seems there is only one Maxxair II model and the only choice you have is white, almond, black, or smoke in color. I assume you have the factory vents on your Camplite.

Word to the wise... check your roof before you buy the larger maxxair II.   My BR vent was close to the sewage tank vent.  I had to trim the edge at one corner to get it to fit a camco brand one which is smaller.    I don't think the maxxair II would have worked on that particular vent.

Yep, factory vents. I'll take a closer look online. Seems like my first search pulled up different shaped hoods.. ?

Ah, yes, the covers come in the original version and version II. I have the original Maxxair type, but the thread was started by Shovelhead with the Maxxair II. They are different shapes, and based on what tbones noted, you'll need to check to make sure version II clears the sewer vent. Or if you have the same trailer as Shovelhead, see if his works first!

Thanks Merlin - they all seem to work with our CL air vents and the vents are pretty much standard size from what I can tell (14x14)... ordered the smoke ones today.

[shovelhead]

It doesnt look as though there is sufficient space for the vent over the bathroom  (21RBS).  Thats why I only ordered 2.  The front vent and the vent above the fridge area has plenty of space.   I'd like to find a vent cover that is smaller and use it for the bath vent.
