Abstract
A truck cab is supported from the vehicle chassis at six points, two points being at the front corners of the cab, two points (mid-mount) being midway between the front and the back of the cab along the exterior sides and two points being along the rear sill of the cab. The front support points are fitted with conventional rubber mounts supported from chassis frame rails. Left side and right side single leaf springs are attached between one each of the mid-mount support points and the rear sill support points. A single shock absorber may be fitted centered along the longitudinal center line of the vehicle under the rear sill, bracketed by the rear support points.
