Get a brochure of each coach. The Newmar brochure is available online. Compare the specs, features and floor plans. Newmar does have Comfort Drive. I'm positive there are many more differences that are too numerous to retype into a post. Going to the factory and taking the tour, several times, will also open your eyes. Newmar will customize more than any manufacturer with a price below $1M.
