If you are jamming things onto your roof - solar panels, whatever - the MaxAir takes up a larger footprint, so that might be an issue to consider. QUOTE]
Only if you install other than the rear of the van. Same hole size but there is more overhang to the rear. Whatever fan you choose, I recommend installing one even for those that just use their Sprinters just for cargo.
Silly response.The only (2) reasons to get a Fantastic is you don't know better, and/or you can't afford a MaxAir.
Thank you.... for validating my points.Silly response.
Here are my reasons for choosing the Fantastic Vent over the Maxxair:
1) The 4000/1250 model is all you really need and it's easily had online for $100-$130 shipped.
2) Not only does it sit closer to the van roof than the Maxxair but I also got the flat lid, which makes it even less noticeable on the roof. Best stealth option as it is only ~3 inches high when closed.
3) It let's a lot of light in. Maxxair does not let light in.
