Class Cs like a 31L have larger frontal area because they are 99 inches wide versus Axis/Vegas at 94 inches. Height are similar, so about 5% difference.

Class Cs like Chateau and Four Winds also have squared-off panels on either side of cab facing directly into wind, and the overhead bed area that extends beyond windshield normally makes for a higher coefficient of drag.

The Axis/Vegas “should” be significantly more aero than a 31L or other large Class C. The front of an Axis/Vegas is also unusually tapered due to narrower front track (compared to other Class As), which should reduce overall drag.
