Have the dealer switch the rear-air suspension dual-leveling valve to a single.
It’s not optimum to run a dual leveling valve because if one side fails, the load can shift, creating a surge condition that can push you off the road. Especially, going around a sweeping, off-camber corner. A failure with a single leveling valve will simply lower the chassis at a controlled rate.
It’s just best practice. Is there a plague of Kenworth tanker rigs falling off the road with dual leveling valves? Of course not.
That is all. Carry on.
