I am planning to get Maxxair vent covers on my class C.Question 1: It looks like the Maxxair original is about $31 online & the Maxxair II is about $40 online. I'm guessing that people would generally recommend the II over the original for only $9 more but please advise if you have an opinion on this.Question 2: We have 2 roof normal roof vents, 1 Fantastic Fan vent, & 1 bathroom fan vent. I am planning to put the Maxxair on just the 2 normal roof vents. A local RV service place I trust said not to put one on the Fantastic Fan vent (unfortunately, I can't remember the reason why). Do people have them on their Fantastic Fan vents - if so, do you like them there or not? It seems to me like I'd want one on the Fantastic Fan vent but was told not to for some reason.Thanks!

#2 I had a Maxxair on my Fantastic Fan and it was a little small so that when the lid opened on the fan it caught on the cover and striped the lift gear out.Fantastic Fan makes their own cover I would recommend that as it is proper sized and flows more air.

A regular Maxxair vent cover is not tall enough to allow the FantasticFan door to open all the way. Causes damage.

Why you should not put a Cover on a Fantastic Fan.There are a few different models of Fantastic Fan..Some of them have electric motors that raise and lower the cover. At least one you open and close by hand.The problem is the covers, are NOT large enough to allow you to fully open the cover in many cases (MaxxAir II may be, Not sure) and this can lead to cracking of the lid.If the FF is an automatic (Powered head) model the cover prevents it from sensing Rain.And in all cases the cover CAN restrict air flow...Slightly.

If you want a cover for the Fantastic fan, you'll need the Maxxair II to allow the fan lid to fully open. We have 2 Fantastic fans and the Maxxair II covers on them and they work great for us. The rain sensor won't work with the cover, but why would you need that?

Having 4 roof vents in mine I use the Maxx Air original on 3,one over the bathroom vent that has a fan,and the Maxx Air Fan Mate over my Fantastic Fan.They all work great and I am able to open them all at any time Rain or Shine.

We had two fantastic fans installed on our Class C. We opted for the Ultrabreeze cover by fantastic fan. A little more in cost, but supposedly works better. I have nno idea if is does or not, but to me, it looks better. I even bought one and had it installed over the bathroom fan.
