A cylinder mount assembly for a slidably adjustable fifth wheel hitch assembly comprises a slidably adjustable fifth wheel hitch assembly, a cylinder mount, a hydraulic cylinder, a first longitudinal support, and a second longitudinal support. The slidably adjustable fifth wheel hitch assembly has a first longitudinal position and a second longitudinal position. The cylinder mount is disposed adjacent at least two sides of a first frame cross member. The hydraulic cylinder is disposed between the cylinder mount and the slidably adjustable fifth wheel hitch assembly, and is attached to the cylinder mount. The first longitudinal support is disposed between the cylinder mount and a second frame cross member. The second longitudinal support is disposed between the cylinder mount and the second frame cross member. The cylinder mount is adapted to move laterally along the first frame cross member.
