The next step is to prepare the new roof vent for installation.
How to replace rv roof vent.
Straighten the tabs that go into the old vent and then take off the lid.
This is actually a pretty easy step that only consists of applying some putty tape along the screw holes that will be facing the roof of your rv.
Remove old garnish or cut new opening.
Once you are home get back onto the ladder and remove the pins from the hinge of the old vent.
If you are replacing an existing vent remove the old trim ring garnish piece from inside the rv.
By doing this you re ensuring extra strength for holding the roof vent in place.
