Hey all! Just got done towing a 30ft camper from NC to CA with our 2013 GL450. Was not sure how well it would handle that trip, but in hindsight I wouldn't have wanted any other vehicle for the job. Only problem is now that we are completed the trip, the GL450 seems super stiff over all bumps. I know that the air ride stiffens up for the added weight on the rear end. Feels like the GL still thinks it's towing something. Haha. Does anyone know how to clue the vehicle in to let it know that it's ok to go back to "normal" mode now? Thanks in advance.
