According to the specs on the heritage site the 5000 and 6000 series trucks had a front axle rating of 4500lbs. So for these "2 ton" trucks the axle could handle 2 1/4 tons. My 5700 has a 160.5" wheelbase and a 16000lb. GVWR, for this truck it should have 99% of the load on the rear and 1% on the front axle at the max GVW. Lots of good stuff in those charts.
