Thanks again everyone. The new shower skylight arrived yesterday and I got it installed and caulked. Sharon won't be happy with my messy caulk job, but it's done. When it comes to caulking, try as I may, I end up with more on me than on the project!
I'm so glad I got a new skylight to match all the other new vents on the roof. Many thanks to the folks at PPL Motor Homes parts department! Good prices, fast shipping and real humans to answer questions.
