Trailair Flex Air, Tri-Glide or eariler, auto height
I was thinking, would there be any advantage if one added a ride height valve to a Trailair Flex Air or earlier hitches so the airbag would always be at the correct height?
It wouldn't require any real modification to the pin box other than finding a way to mount the valve. The valve could be mounted using clamps and the output of the valve just connect to the existing air bag filler. This way it could be removed at any time.
