Could Hendrickson's Zero Maintenance Damping system be the best-riding trailer air suspension ever? Equipment editor Jim Park takes one on three-way comparison test drive. He says its certainly a contender.
Smart, but wouldn't it make more sense to flip the airbags upside down and do the dampening on the part of the chassis rather than the arm, in theory that would reduce the unsprung weight and airflow into the damper part would be smoother as the road vibrations are isolated through the bag. Also, what's the cost of this system compared to a regular trailer, I would think since dampers are difficult to manufacture this system should not cost more than a regular suspension?
