Roof vents are essential in maintaining good air flow in your camper trailer. Vents also ventilate the camper, removing the stale musty air that accumulates in the camper during hot weather or when it is in storage. Old vents were hand cranked but newer versions can be controlled electronically. You can install a vent in a short amount of time by following the manufacturer's instructions. Instructions will vary according to your specific type of camper trailer.

    Insert the jigsaw blade into the hole in the roof. Cut along the marked lines. Remove the roofing material.

    Go inside the camper. Trim the interior facing to fit with the utility knife. Insert the facing around the vent.
