The MaxxFan was dropped in place, secured with the supplied screws, and a healthy layer of self-leveling roof sealant applied over the screws and mating surfaces to ensure no future roof leaks. Luckily for us, the trailer was pre-wired from the factory for a vent fan, so all we had to do was make two connections for the DC-powered MaxxFan.

The MaxxFan comes with a cut-to-fit trim ring. All we had to do was cut the new part to match the old part’s height. A jigsaw or body saw works best here.

Should the fan loose power unexpectedly, there is also a manual control for the lid on the opposite side of the fan.

We liked the backlit screen, especially at night. With the lights off and while in bed, adjusting the fan settings did not necessitate climbing out of bed or even finding a flashlight.
