Decided instead of just updating our factory OEM 2019 320s fantastic fan , I choose to do a complete removal and install of a new MaxxAir 7500K (top of the line one) . The factory Fantastic fan was
OK , but I grew tired of the manual opening , no remote control and no rain cover . Just decided to go with the MaxxAir .
This one ...........
Also used this self leveling Lap sealant , and butyl tape .......
First went about removing the Factory Fantastic Fan, and it was quite a job ! They really seal that thing in place . LOTS of butyl tape and lap sealant .
Was SHOCKED when I found out nuCamp uses
NO screws in the fan at all !
Picture of the roof with the removed fan showing
NO screws !!! (and some small scratches from removal, but I knew the new fan would cover it all . That thing was hard to remove!
PPG DX440 adhesive/wax remover makes short work out of getting all the old butyl tape and sealant off the roof with no harm to the aluminum roof skin or paint .
Next , was to set the new MaxxAir fan "frame" and carefully center it ........and drill 16 holes through the roof ..........GULP !
(notice the aluminum framing that surrounds the fan opening ........talk about nuCamp quality , wow ! All the holes/screws are directly through the roof, into the aluminum frame .
MaxxAir mounting frame installed, with some nice thick butyl tape underneath (you can kind of see it sticking out) .
Now to tape of the area for the self leveling Lap sealant to flow , and hopefully not make a mess . I Cut the old lap sealant away from the solar panel, so it "butted" up to it and sealed properly .
Now for some lap sealant .........grey to match the factory sealant . Finished and tape pulled . You have to work pretty fast with this lap sealant .........but not
too fast . Definitely an art to getting this stuff to look "neat" !
Just about finished ...........wiring was simple . Just two wires - easy peasy . Had to trim the "beauty ring" next . Just an FYI , the measurements were exactly 2.5 inches .
Here are some finished pictures , inside and out . Also some pics showing the fan open and closed ..........
Main reason for the switch from the factory OEM Fantastic Fan to the MaxxAir was ........
Pros ........
1. Ability to leave the fan open in the rain
2. Remote control opening
3. The remote control itself for all the settings
4. Less power draw
5. Thermostat control if needed
6 . Liked the sleek look
7. Ability to leave the fan open when traveling when needed
8. Fan works as a ceiling fan when closed, to help keep heat/ac circulating
9. I am in the business , so to speak, and my cost was not that bad compared to the Fantastic fan upgrade route .
10. Remote control
10. REMOTE CONTROL !
10.
REMOTE CONTROL !!! And the minor cons ......
1. Partially blocks the solar panel when closed
2. Lid/Cover is not as "dark" as the factory Fantastic Fan
3. Manual open/close knob sticks down "slightly" more than the factory fan (might remove it) .
It works GREAT , and it was worth the cost and installation time.
Install was not
easy , as you cant really work "on" the roof like most RV's . There was a
LOT of climbing up ladders, from side to side to install . Total install time was about 3-4 hours , taking it slow .
In the end, it was worth it .........LOVE the new MaxxAIr !
Just the ability to let the fan run on hot days to keep the cabin from getting hot (and not worry about rain) is awesome !
Oh , and yes ...........I KNOW it very slightly blocks the solar panel when the fan is CLOSED . Not much of a concern for our camping style . When its open , the solar is totally unblocked . Also, we dont boondock too much , and almost always have shore power . If we need more solar, I can always add a portable unit , in addition to the factory solar .
