Maxxair 00-04000k MaxxFan RV 12V Roof Vent - White - Manual Opening - Ceiling Controls
This roof vent gives you a high level of control over ventilating your RV or enclosed trailer. You can set the fan's direction to exhaust hot, stale air or pull in fresh, cool, outside air. You can also adjust the fan's speed to control the volume of air movement. Or you can set the thermostat, and the fan will automatically vary its speed to keep your trailer comfortable, freeing you from the trouble of constantly adjusting the fan yourself.
With two lifting arms, the MaxxFan roof vent provides sturdy support for the lid. It's strong enough to handle high winds and to stay fully open while you're driving. Unlike typical vents that use just one arm, this one won't annoy you with fluttering sounds or make you worry that it might blow away.
All the keypad controls are located together for convenience. The flush-mount surface makes cleaning a breeze. The adjustment knob rotates to allow you to raise and lower the lid. You can lock the knob when the lid is fully opened or closed, ensuring that it will stay in position.
I first ordered another fan that was too big for my van. This one works great. I've only used it in low power settings and it doesn't seem to draw much energy but it moves air around really well. Also of note I picked this up at their warehouse and it was nice to put faces on this store. It's easy to get a sketchy feeling to order parts from what seems like just another rv parts website, but I've met them and they are nice and helpful people, and I'd order again from here without hesitation.
