Our 04 Allure, built Sept 2003, had the two standard Fantastic Fans. Both performed well for us.
I added the Maxx Cover that would worked with he Fantastic - on the front unit, in our coach over the galley.
I did not put one on the rear fan, which was over the Water Closet across from the Shower and Bathroom Sink, our coach. The reason for not putting the Maxx Cover over the Fantastic, was because of solar. (As mentioned in earlier posts, the solar shading is always something to be guarded
The solar panels in that section, X's 4, are on the Passenger side, and via a raised rail residential rack, spanner the top of the shower Solar Dome. Real cuts down on Solar Gain, as the panels shade the dome. And significantly quitter during rain/hail storms
! Potentially, it's slightly warmer during cold spells too. (Though on real cold extremes, we do use shower curtain rods in the dome, with insulation, to help from the cold.).
I decided to add the MaxxFan in the water closet (Driver's side.) as I wanted to have the 'reverse fan' capability, to help pull cool air in at night while sleeping. The real bonus is with the fan closed, zero problems with shading of the solar panels. And even with the fan running, and in up position, it's a smaller overall shadow impact potential, then teh 'fixed' Maxx Cover over the Fantastic would have been.
Our first full year of travel with it, so sort of early to say how well it holds up. But so far, we like the remote, the reversible fan, and no problems so far
And, I'll share that the only time I called Fantastic Fan for help, even under the not so new ownership - they were very helpful.
So, no complaints with either
