My question is, what year did Scamp
upgrade the roof to be stronger?
Jamie -- the problem, I think, with older eggs is that the roof doesn't have enough arch to make it strong. It's relatively flat and thin. Thin is ok if there is sufficient arch. However, the walls, being vertical, and the edges of the roof, being tightly arched, should be plenty strong. What you are proposing is to actually remove the weakest part of the roof, and replace it with a proven-strong roof. This new roof will be sitting atop the strongest areas of the existing camper. Don't mistake me for an engineer, but I think if anything, you'd have a stronger roof. My bigger concern would be the increased flex at the corners. When you cut the hole, allow sufficient radius at the corners so they don't flex and crack. And again, by glassing up a lip at the top for the Westie top to fit over, you'll be further stiffening it, both for snow load and flex. I don't want anyone to say, "Well, Paul told me it would work", but I think it should.
