MaxxAir Maxxfan Plus 4000K
#6 in Open lidFull review
For owners who want strong two way airflow and a thermostat without paying for a motorized lid. Pair it with a separate cover if it has to run in rain.

3.2/5
For a low cost upgrade from a plain vent that still blows in and out at ten speeds. Buyers who leave the RV unattended should pick a fan with a rain sensor.

For buyers who find it cheaper than the 10 speed Plus 4000K at the time of purchase; otherwise the 4000K does the same job with finer speed control.
