Thor Super C Chateau in Type C Motorhomes Posted September 13, 2015 · Report reply Our Bounder is gas...2006 33R, not sure of the wheel cut. It's the height of the Bounder rather than the length that we're concerned with. We like the idea of less steps and being lower to the ground. With bad knees, the steep steps of the Bounder are getting more difficult to up and down. Haven't read great reviews on the Super C so may go back and look at more A class coaches.
