With the Ultra-Breeze you have to scrape away the old caulk to get to the screws. You the remove a screw and re-use the hole. The MaxxAir requires drilling into the side of the vent in order to mount clips. To me the MaxxAir system seems like it would be easier to install. An added advantage is that you wouldn’t have to buy any Dicor to reseal the vent flange. I installed the MaxxAir II on our last trailer. The installation wasn’t bad, but I wasn’t happy that the vent lid was somewhat limited in how high it could be raised
Both the MaxxAir Fan Mate and the Ultra-Breeze are the same height (10-1/4”), though I suspect the Ultra-Breeze might allow the vent lid to open up more due to the shape.
I’m leaning towards the MaxxAir.
I had considered everything you mentioned. I actually prefer utilizing existing mounting holes versus drilling new holes (even if it is just into the vent frame).
I already have the Dicor lap sealant, so not a deal breaker to seal up the Ultra Breeze mounting brackets.
Removing the old sealant should not be to big of issue, will it take longer to install than the MaxxAir, absolutely. But I am ok with that.
And finally, I prefer the look of the Ultra Breeze vent cover. I will add UV protection to the vent cover as insurance, but I don't think there will be an issue. If there is in the future, I will consider the MaxxAir brand as a replacement.
