Look like there is glad wrap (or similar) on the fan lid. Why?

Haha. That’s when I first cut the hole I set it in and snapped a pic.
It still had the shipping protection paper stuff on the top. Haha.

Thanks for the photo! I guess I made the wrong choice buying the Dometic, ha! It’s noticeably taller.
A pretty lengthy fan conversation went on here when we decided to cut roofs a while back. Try starting on
page 25 or so, maybe.

im thinking of offsetting the fan to the right so i can leave one panel out and vent with dogs in back. anyone think of why that may be a bad idea?

Someone did that on the drivers side rear.
Can’t remember who it was though… 
BTW. Update on the trip. No condensation with windows cracked in 18-19F first night. Went with one window cracked and one closed the second night in 30-32F and no condensation either. Seems that if the ambient temp and humidity inside and outside the roof/tent are the similar then there is nothing to condensate. Again this was just 1 person. When I had two people and a dog and both windows closed the condensation was unreal, but also dogs will add tons of humidity into a space this small over the course of a night. My two cents is depending on your goals and where you live it can be useful, but in a northern based climate you really won’t use it much unless you plan on heating the whole place with the windows closed and cooking inside it etc. I use my gfc like I use a floor tent just a little more flexible in what it can do.

This is my plan as well. But, I’m going to use a marine fan with built in solar and battery. My dog stays in a kennel in the bed of the truck and when it’s humid - everything is drenched.

I’m planning on fitting one of these: https://www.amazon.com/gp/product/B00407CK5W/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
Even solo camping with the windows cracked leads to a lot of condensation for me (tent fabric v2). It’s not unmanageable - I wipe the entire interior down with a microfibre cloth when I wake up - but it’d be nice to reduce it.

Why that one and not the Maxxfan like the rest of us did? Just curious.

I bought the Dometic fan and found it gigantic. I figured I can try this first and if it works, I’ll stick with it. If it does, I’ll enlarge the hole and put a Maxx fan in its place. I prefer the smaller, simpler footprint.

I think that the Maxx Fan is overkill.
If you can use a 6" hole saw it would make the installation easy.
A 6" hole weakens the roof a lot less than a much larger square opening. When it’s shut the leading edge is sloped thereby less likely to get hung up on an obstruction plus not likely to blow open inadvertently. More aerodynamic profile too.
100 CFM < 900 CFM 
Not sure you’re going to notice enough air movement with one of those especially if you’re trying to cool off the tent in the summer months like I do. I’ve been running the Maxxair for 5 months now. No issues. Hasn’t blown open going 100 or anything. Roof doesn’t seem to mind at all either.

Give it a try though. What’s to lose? Like you said you can always make the cutout 14X14” if you find it’s not enough fan for you.
I’m curious to see how it works out for ya.

that is awesome, putting that on my list of mods when mine is finally done
@2ayne, is this the model you got? https://www.etrailer.com/RV-Vents-and-Fans/Maxxair/MA00-04401M.html
I noticed in your post that you said it only extends 1.5" above the roofline, but for some reason the shortest I could find was 2 7/8".
I think I meant that the Maxxfan is approx. 1.5” lower profile at 2 7/8” above the roof than the Fantastic Fan which says online that it sticks up 4 1/2” when closed.
“-The Maxxfan is 1.5” lower profile than the Dometic”
So technically it is 1.63” lower than the Maxxfan, correct?

Ahh gotcha, cool. Really just wanted to make sure I was getting the right one. Thanks!

The weather here has cleared up for the day, so I am going to go for it and install the fan. @2ayne, did you use a jigsaw to cut the hole? Would you have changed anything about your install that you haven’t mentioned yet? Thanks again for all the info!
