I'm not familiar with Maxxfan. I used the FAN-TASTIC 3 speed which takes a 14" X 14" hole. Let me say, when you crack the front windows and turn the fan on low it becomes a wind tunnel. The other day I accidentally left it on low for over 18 hours. I checked my battery voltage when I realized it and it was at 12.33v normal is 12.44v very efficient.
I like my fan so much I want the fully automatic one now. Senses rain and closes, opens via remote control, variable speed control. Nice.
Keeps my van nice and cool even on the hottest days.
