Have a question about re-arching the roof on my 87 Sunrader. I have a sagging roof that I need to raise. I jacked the roof up under the AC area until it started creaking, at which point it looked like it more or less matched the arch at the front and rear of the roof. However when viewed from the exterior there is still dip at the edge of the roof line. My question, having never seen an original roof, is whether that dip is supposed to be there or whether I need to jack further. I have attached some pictures to help clarify what I mean by the dip. Thanks for any and all help.
