Okay, still beating this fan topic to death--I have my fan and am planning on installing it in the next day or so. I was reading the instructions and they use the foam gasket with silicone around the edges. I know Larry and others use putty tape, which is what I'm planning on doing too, but do you use that in the place of the foam gasket and just throw the foam thing away? And any tips on installation??
ETA: I think I found my answers on the old Shasta forum but if anyone has any tips that may not have been in the other forum please share!! Lol

I have been using the foam gasket on most of my trailers. Recently, an Airstream roof was very curved, so putty was a better choice. The foam gasket is actually for EPDM rubber roof installations, but works very well on vintage trailers with reasonably level vent openings.
NO SILICONE sealant. Dicor self leveling lap sealant is much better and removable for repairs.

This is a great time to check to make sure that there is a "crown" on the framing for your vent. If there isn't one, install one first. A crown is just a square frame that sets on top of the regular roof framing around the hole and it holds the roof metal up 1/2 to 3/4 inches above the rest of the framing right there at the vent causing the rain to run off and down from the vent. This prevents puddling. Easy to do from the inside by just sliding four pieces of wood in under the skin with glue and then staple from the inside for a little more holding power. The inside trim will cover up the staples.
My videos show the crown where ever you see me replacing the ceiling panels.

We added a crown Larry-just because your videos said to. Ot actually DID have a little crown on it though and did't appear to have leaked around the vent. I think all the damage came from leaving the vent open. But we got it all replaced and nice looking. Thanks!!
