Royf did a good job of regurgitating the payload specs.
But what he didn’t mention is that the only differences between a 250 and 350 srw apples to apples is a heavier duty rear axle and greater spring capacity.
Combined with the fact that some 3/4 tons are still set at 10klb gvw and even the 10.5 sterling axle in the 250s is rated for almost 10klbs, the physical differences are almost a moot point.
A fact that many cannot understand or refuse to believe.
So Dave just because you think you did something wrong by not specifying a gvw ? Package, it doesn’t matter. Only low end factor on your truck, presume it’s old or base model, is the 17s.
