Abstract: An engine heater system for supplying compressed air to an air brake of a vehicle. The engine heater system including a gas turbine. A compressor fluidly coupled to an air reservoir of the vehicle. The air reservoir fluidly coupled to an air brake of the vehicle. A shaft rotatably attached between the gas turbine and the compressor, and when the gas turbine rotates the shaft, the compressor provides compressed air to the air reservoir of the vehicle for operating the air brake of the vehicle.

Abstract: An engine heater system for heating a diesel engine of a vehicle. The engine heater system including a gas turbine. A heat exchanger communicatively coupled to an exhaust of the gas turbine. An electric generator including connection members to couple to a battery of the vehicle, and a shaft rotatably attached between the gas turbine and the electric generator. The heat exchanger utilizes the exhaust of the gas turbine to keep the diesel engine of the vehicle within a desired temperature range, and the electric generator charges the battery when the gas turbine rotates the shaft.

Abstract: The step assembly (10) includes a housing (12) which is mountable to a recreational vehicle, typically underneath the door of the vehicle. A pair of linkage arms (14) and (16) are rotatably coupled at their lower ends to each side of the housing (12). The step assembly (10) contains an upper tread assembly (18), a center tread assembly (24), and a lower tread assembly (34), respectively including an upper step (20), a center step (28), and a lower step (40). The upper ends of the linkage arms (14) and (16) are rotatably connected to the upper portion of the upper tread assembly (18). The center tread assembly (24) is slidably engaged with the upper tread assembly (18) through a slideway assembly (26). The lower tread assembly (34) has a lower tread pivot arm (38) which is rotatably coupled to the center tread assembly (24) by a pin (30) mounted on the center tread assembly.
