Truck stop scale & u will know the weight. Pull in the scale, mash the button. Tell the fuel desk a name, trk & trailer number. Can make one up like number f250 or c2500 etc. go in pay for the scale ticket & u know what weight is on what axles. Re weighs same day are usually a dollar each. Scale platform will be divided for steer axle, drive axles and trailer axles. .... or if u know someone at a local business with truck scales that will give u the ok to use theirs, or a co op has scales sometimes that are public/pay
