001/2002 MODEL YEAR GENERAL MOTORS TRUCKS CONSUMER INFORMATION TRUCK-CAMPER LOADING Consumer Information Regulation 575.103 issued by the National Highway Traffic Safety Administration requires manufacturers of trucks capable of accommodating slide-in camper bodies to provide information concerning proper load and proper load distribution in truck-camper applications.
TRUCK-CAMPER LOADING Consumer Information Regulation 575.103 requires manufacturers of trucks capable of accommodating slide-in campers to specify the vehicles’ Cargo Weight Rating (CWR) and the longitudinal limits within which the center of gravity for the Cargo Weight Rating should be located.
TRUCK-CAMPER LOADING Loading Instructions – When the truck is used to carry a slide-in camper, the total cargo load of the truck consists of the manufacturer’s camper weight figure, the weight of installed additional camper equipment not included in the manufacturer’s camper weight figure, the weight of camper cargo and the weight of passengers in the camper.
TRUCK-CAMPER LOADING DEFINITION OF TERMS For the purposes of calculating Truck-Camper Loading in this book, listed below are some common terms and abbreviations: Cargo Weight Rating (CWR) – means the value specified by the vehicle manufacturer as the cargo-carrying capacity of a vehicle in kilograms (pounds), exclusive of (minus) the weight of occupants, computed as 68 kilograms (150 pounds) times the number of designated seating positions.
