Just brought the Safari home today, waxed it, flushed the plumbing, and went to check the roof. My vent oddly enough is not caulked. I has what appears to be a mortite type material. It did crack, but was easily smoothed out. Still, I looked at my roof vents and such and the caulking is not really doing all that well. I am thinking I have some roof work to do at some point.
Also on a side note, I went around the Safari today with Acryl-R and was astonished to find that a handful of places needed some help. More than I thought I'd see in a 5 year old unit.
