A fire apparatus includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a ladder assembly coupled to the chassis, and a stability system. The stability system includes at least one of (i) a front downrigger coupled to the chassis, (ii) a rear downrigger coupled the chassis, or an outrigger coupled to the chassis. The stability system is controllable to facilitate leaning the fire apparatus at least two degrees relative to a ground surface while maintaining full operational capability of the ladder assembly.

A lifting system for generating a lifting force on a portion of a vehicle includes a vehicle wheel and a force-generating mechanism structured to be received inside a rim cavity of the wheel. The force-generating mechanism is also structured to be operably connected to a frame of a vehicle. A bearing member is operably connected to the force-generating mechanism. The bearing member is structured to transmit a force generated by the force-generating mechanism to a surface in physical contact with the bearing member. The bearing member is also structured for operably connecting the wheel to the force-generating mechanism. Force applied by the force-generating mechanism may be sufficient to lift a portion of the vehicle off of a ground surface, or the force may only be sufficient to apply a parking brake force without lifting the vehicle.

The invention comprises a seating plate including a concentric swivel leveler to be used for leveling a trailer on an uneven ground surface by inserting a connected trailer jack into the swivel and establishing a stationary position wherein the trailer is substantially level. In certain embodiments, a spacer is also provided with a receiving well for the swivel such that a height of the seating plate above the ground surface is increased such that the trailer jack need not be extended as far as it would but for the spacer. A spacer may be of durable material and includes reinforcing support members help support large loads. In certain embodiments, the swivel may be fastened to the spacer using nuts, bolts and the like so the swivel may swivel about the receiving well while the seating plate maintains a height above the space top to allow for the swiveling action.

A recreational vehicle includes a frame, left and right air suspensions, a front jack, a tilt sensor configured to measure lateral and longitudinal tilt data associated with the frame, and a controller. The controller is configured to receive the lateral and longitudinal tilt data to thereby level the frame laterally via operation of the left and right air suspensions and level the frame longitudinally via operation of the left and right air suspensions and the front jack. Methods for performing a leveling operation include utilizing left and right air suspensions of the recreational vehicle in combination with operating a front jack of the recreational vehicle until the recreational vehicle is level along lateral and longitudinal axes.

A reusable vehicular jack pad system, including a plurality of jack pads, each respective pad further including a top face, an oppositely disposed bottom face, a jack-engaging assembly operationally connected to the top face, a palm portion, and a toe portion extending from the palm portion. Each respective jack pad is shaped like an animal paw. Each respective bottom face is contoured to leave a paw print in soft ground. Each respective top face is contoured to stackingly engage a respective bottom face.

Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes a frame having an upper ledge; an extendible leg coupled to the frame, the upper ledge being vertically movable to selectively engage and disengage an underside of a trailer parked on a driveway based on movement of the extendible leg relative to the frame; a wheel connected to the frame, the wheel to remain at a substantially fixed distance from the upper ledge as the upper ledge is vertically moved.
