Yeah, it really is very easy to do.... well a bit of work with the putty knife pulling away the old caulk, but if you have a drill/driver and a caulk gun that's pretty much all the skill you need.
You don't have to cut the roof or anything, they fit in the same hole.
Newbie here. Just purchased a 22E today! I noticed it had 2 fans (upgrades, dk if so), but they were labeled "attic fans'. Should we have anything done to those; are they similar to fantastic fans, and do they have covers. We take possession next week, so a good question to ask them.
My Class C mc has a 4 x 4 rear bumper tube used to house the sewer drain hose. I do not use it for the sewer hose but use it for my fishing rods. Anyway, I found a few wasps had built a nest inside the tube and accessed the interior through the black plastic end caps vent holes. I had some self adhesive window bug screen repair material and scissor cut two pieces and stuck over the holes and seem to have solve the problem of the wasps. Maybe an ideas like this may have some merit.
