The specified payload may be decreased in the amount equal to the weight of the extra equipment specified and installed such as racks, utility cabinets, etc. In no event shall the pay
11、load requirement be decreased by more than 30 percent. The payload in pounds shall be calculated as the difference between the G.V.W.R. of the class vehicle furnished less the curb weight (see 3.6.1). The difference shall be termed the net payload. 3.6.3 Gross vehicle weight rating (G.V.W.R.). The v
12、ehicle gross weight rating shall be equal to or greater than the combination of weights of the vehicles curb weight (3.6.1) and the minimum payload specified (see 3.6.2). Manufacturers shall provide a rating label showing the actual G.V.W.R. of the vehicle furnished. 3.6.4 Dimensions. Vehic-le dimen
13、sional requirements are specified in Table I for each type and class vehicle. The OL (overall vehicle length) and wheelbase dimensions shall permit the distribution of weight to allow for proper steering control, and traction for the drive wheels under all operating conditions. 7 .
