When we were looking two years ago at the Hershey show we were talking with a dealer that sold the two products you mentioned. The salesman was actually a tech that worked at the dealership. He told us the Rockwood had 1.5" walls and the wildcat had 2" walls. We also liked the larger tank capacities, 16" tires, and larger HW TANK. We went with the Wildcat, the Wildcat Maxx is not available here in the Midwest .
