It has 10 different fan speeds, so you can control the airflow and noise levels. The fan fits standard 14-inch by 14-inch RV roof openings. It has a white lid and is flush mounted with an air intake and exhaust. One of the best things about this fan is that the blades are virtually silent on lower settings without sacrificing airflow. The vent lid also opens manually and has double struts for durability. In addition, the remote-control models include backup controls on the ceiling for added convenience.

One problem with this product is that the instruction manual covers a range of fan models, which can be a hassle during installation. Also, the fan does not include an integrated rain cover, and only one made by Maxxair will fit so your options are limited.

It fits standard 14-inch by 14-inch roof openings, and the fan is made of galvanized steel with a mill finish.

The fan also includes a removable screen, which makes it easier to clean. Overall, it looks just as good and works nearly as well as higher-end, more expensive units.

However, the fan does not come with screws, putty, etc., which means you need to buy these items separately. Also, the fan is either on or off, and you can't adjust the speed of the fan blades.

The Fan-Tastic 12V three-speed fan has a low amp draw, so you can use it without accessing the main power supply. It’s made from ABS plastic and fits a standard 14-inch by 14-inch roof opening. This universally designed fan accommodates most vans, travel trailers, and small motorhomes, and it has an integrated lid. The unit is made of UV-resistant ABS plastic. The fan is durable and quiet. It's a great fan to use off the grid and in situations in which air conditioners are not permitted. It has a locking lid and will not operate if the roof is closed. The screen is removable for easy cleaning, and the manufacturer provides a one-year warranty.

Unfortunately, the knob that opens and closes the lid can wear down after sustained but not excessive use, so over time it can be hard to grip and operate the vent cover. Also, the fan blades are not reversible and only pull air in.
