I believe they are checking or adjusting the Thrust Angle to ensure the rear axle is properly aligned to the front axle/suspension. Improper thrust angle will result in a vehicle pulling sideways. Ever see a car going straight down the road at an angle where, when the have the wheel pointed straight, you can see all four tires?
Verification of the Thrust Angle is especially important on motorhomes that have had a chassis stretch. 1/8 inch of additional length of frame metal on one side would throw out the thrust angle significantly. One would think that MORyde or whoever does the frame extensions would be required to checking the thrust angle prior to shipment.
