Description

CROSS-REFERENCE TO RELATED PATENT APPLICATIONS The present Application is a Continuation of U.S. patent application Ser. No. 18/143,188, filed on May 4, 2023, which claims the benefit of and priority to U.S. Provisional Patent Application No. 63/339190, filed on May 6, 2022, both of which are incorporated by reference herein in their entireties. BACKGROUND The present invention relates generally to a refuse vehicle. Refuse vehicles collect a wide variety of waste, trash, and other material from residences and businesses. Operators of the refuse vehicles transport the material from various waste receptacles within a municipality to a storage or processing facility (e.g., a landfill, an incineration facility, a recycling facility, etc.). SUMMARY OF THE INVENTION One embodiment relates to a refuse vehicle. The refuse vehicle includes a chassis, a body coupled to the chassis, a lift arm assembly coupled to at least one of the chassis or the body and selectively repositionable between a first position and a second position, a lateral member coupled to the lift arm assembly, a set of bump plates coupled to the fork, and a lateral stabilizer assembly coupled to at least one of the frame or the body. The lift arm assembly includes a first arm, a second arm, and an implement coupled to the first arm and the second arm. The lateral stabilizer assembly includes a lateral stabilizer and a backer plate. The lateral stabilizer is configured to support the lateral member when the lift arm assembly is in the first position. The lateral stabilizer assembly is configured to prevent lateral sway of the implement when the lift arm assembly is in the first position by the lateral stabilizer coming in contact with the set of bump plates. At least one embodiment relates to a lateral stabilizer assembly including a lateral stabilizer, a backer plate, a spring positioned between the lateral stabilizer and the backer plate, and a down stop defined within the lateral stabilizer and configured to support a lift arm assembly. The lateral stabilizer is selectively repositionable between an extended position and a retracted position. The lateral stabilizer incudes a down stop. The backer plate includes one or more apertures and the lateral stabilizer is mounted to the backer plate. The down stop supports a lateral member when the lift arm assembly is in a transit position. The lateral stabilizer assembly is configured to prevent lateral sway of the lift arm assembly by abutting a set of bump plates positioned on the lateral member. At least one embodiment relates to a refuse vehicle including a chassis, a body coupled to the chassis, a lift arm assembly coupled to at least one of the chassis or the body, a lateral member, a set of bump plates fixedly coupled to the lateral member, and a lateral stabilizer assembly coupled to at least one of the chassis or the body. The lift arm assembly is selectively repositionable between a transit position and a working position. The lift arm assembly includes a first arm, a second arm, and an implement coupled to the first arm and the second arm. The lateral member is positioned between the first arm and the second arm. The set of bump plates are positioned a distance away from one another. The lateral stabilizer assembly includes a lateral stabilizer, a backer plate, and a spring positioned between the lateral stabilizer and the backer plate. The lateral stabilizer is selectively repositionable between an extended position and a retracted position, and includes a down stop. The backer plate includes one or more apertures, the lateral stabilizer is mounted to the backer plate. The spring is positioned between the lateral stabilizer and the backer plate. The spring is configured to selectively reposition the lateral stabilizer between an extended position and a retracted position. At least one embodiment relates to a lateral stabilizer assembly including a lateral stabilizer, a backer plate, an actuator positioned between the lateral stabilizer and the backer plate, and a down stop defined within the lateral stabilizer and configured to support a lift arm assembly. The lateral stabilizer is selectively repositionable between an extended position and a retracted position. The lateral stabilizer incudes a down stop. The backer plate includes one or more apertures and the lateral stabilizer is mounted to the backer plate. The down stop supports a lateral member when the lift arm assembly is in a transit position. The lateral stabilizer assembly is configured to prevent lateral sway of the lift arm assembly by abutting a set of bump plates positioned on the lateral member. At least one embodiment relates to a refuse vehicle including a chassis, a body coupled to the chassis, a lift arm assembly coupled to at least one of the chassis or the body, a lateral member, a set of bump plates fixedly coupled to the lateral member, and a lateral stabilizer assembly coupled to at least one of the chassis or the body
