Default Here's A Way

First, it requires two people. Take a straight edge, such as a 2X4, and place it across the roof. One person on each end, drop a tape measure from the bottom of the stick to the roof of the coach. Adjust the straight edge until the measurement is equal on both ends. Now move towards the center, say 2-4" and repeat the measure, etc. When you reach the center, you will have created a profile of the roof curve. Transfer your measurements onto the rib you are going to cut to replicate the curve. Caveat: The profile of the outside roof must be the same as the inside ceiling.
