thanks for the replies everyone. One other question.....is silicon the best sealant to use around the outside of the vent on the roof to keep water out? I'm talking about as a final step, in addition to the universal installation kit I have with the sticky gasket.
Thanks again.
Not only no, but hell no. :) Don't ever use silicon. I recommend that you use Dicor lap sealant. You can buy it at any RV parts store like Camping World. I've installed four fan-tastic vents over the years and maintained even more and have found that works best.
