I REALLY wanted that Fantastic Fan, but I ended up settling for the MaxxAir. In the end I think it will even out. I just had time getting myself to break that new factory sealed roof sealant. They are rated about the same CFM and the MaxxAir really pulls the air through the camper too. I also like the rain cover of the MaxxAir......but in the end I dont think you can go wrong either way!
