ABSTRACT:
Paired, laterally opposed generally vertical poles mounted at their lower ends to a towing vehicle horizontal frame and pivotable about a horizontal axis, bear a carriage which extends between the poles and is mounted on rollers for vertical movement on the poles. A hitch-ball carrier extends from the carriage for coupling to the end of the mobile home. Paired hydraulic cylinders pivotably mounted to the frame at their lower ends pivot about a horizontal axis parallel to and generally at the same vertical height as the horizontal pivot axis for the poles, have their upper ends, which are extendable, pivotably connected to the carriage. Paired telescoping beam assemblies are pivotably coupled at one end to the horizontal frame at a point spaced some distance from the pivot mountings of the paired vertical poles and are pivotably coupled at their other end to the upper ends of the laterally opposed vertical poles. By extension or retraction of the telescoping beam assemblies and the locking of the same at a given position, the orientation of the carriage and the hitch-ball may be maintained at true vertical on site, regardless of the angle of inclination of the vehicle.
