Anxious to get this bad boy installed :)

It just attaches to the sides of the vent so you shouldn't need to caulk anything.

I had a TT that some previous owner idiot screwed and sealed them to the roof. During a driving rain it filled the inside up until it overflowed the edges of the vent and drenched the ceiling.

There are L-brackets that go under the factory vent. Then you bolt the cover to the brackets. Very easy without a fan. A bit harder if you have a fantastic fan like i do.

And push some of that rain down here.

These allow you to open your vents even if it is raining. Great for storage too as it allows the trailer to breathe a little.

No caulking required. Just a few screws/nuts for the install. Pretty simple. Be careful on that rain slicked roof.
