You might want to check it on a different surface. I thought my DC van leaned to the drivers side until I parked it on a different spot on the driveway.
Saw an ody on the road directly in front of me two days ago and noticed a definite dip on the driver side rear. Rear of the vehicle looked very crooked. Only person in the ody was the driver, an average sized woman. Doesn't seem normal to me.
