Abstract
A suspension system for towed vehicles automatically adjusts for different payloads and road conditions without the need for manual shims used in prior art suspensions. automatically adjusts a mechanical bias on the vehicle to keep the suspension within a preferred ride height range. A hydraulic cylinder between the frames of the towing and the towed vehicles provides a mechanical biasing force to the towed vehicle. A sensor measures the ride height and causes the hydraulic cylinder to retract or extend according to the bias needed to maintain the suspension in the preferred ride height range.
