Maxx Air II fan cover

Published: Last Updated on

For 2017 and older Casitas with the Fan-tastic vent fan, this is a “mandatory” upgrade. The cover allowed us to run the fan in any weather.  We could also leave the roof vent open while in storage for air flow.  Installation was straightforward almost following the instruction sheet.  The hardest part was not falling off the top of the camper!    Instead of following the first part of the instructions and drilling 3/16″ holes for bolts, (there’s no access to put nuts on them), drill smaller 3/32″ holes and use the included screws (2 per bracket) and screw them into the plastic housing. One side is hinged and the other side had quick release pins to easily open the cover to clean.

We started with the smoke colored cover and changed the inside lid to clear.  That combination brightened up the interior.  After we moved to Miami, it let in too much sun!  We swapped over to the translucent white cover and I think it looks a little better and keeps direct sunlight from beaming in through the roof.

Update: These are getting hard to find. As of November 2023, I can only find the solid black ones here.

will this work on my 2003 with fantastic fan? the link to amazon says it is unavailable, do you know if there is an updated version that will fit my 2003? thanks in advance!

Yes it will fit. Finding one is the trick. The whole RV part industry is behind on making stuff.

Thank you so much! Your explainations and pictures make it easy to understand.

I hope you are out there still! I have a 2012. Got the Maxair2. The sealant from the factory is think and uneven but don’t want to break the seal. I have 2 pictures.

You should have to touch the sealant to add the maxx air cover.

Lois McKee October 7, 2022 - 7:47 pm

I took off old sealant and will use Dicor. How thick do I put the sealant on?

Greg Zimmerman October 7, 2022 - 8:22 pm

Not much, just a nice bead and smooth it with your finger.

Very nice idea, Greg. Have you ever upgraded the main roof vent? My knob lift has disengaged from the screw again, so I think it’s time to replace entire unit. If you have any suggestions, I am “all ears”

You can easily swap it out for a new maxx with retractable cover (like the newer Casitas have). The hole is the same size, but you’ll need to drill new rivet holes around the perimeter.
