That classification system and trucks involved is not totally.correct at least from a GM standpoint. If the 5500 is older std cab, that giver went from 19,500-26000. SAME as the 6500. The 4500 was the.class 4 and 5 rig with giver from 14000-19500.
The Allison trans, the 1000 is good to 19500 giver and iirc 30000for gear. The 2000 series.in.Two.different gearing options, with or with out a parking pall, went from 19500-26000 giver with the pall, to 33000 without a pall. Gear was 30k with, 40k or so with out. These two options GM wise wee only.in the 25-55 series. The 6500 and higher had the 3000 series trannies. That series.got you.up into.The 60-100k gvw range. Higher hi p.and torque.input.rating too.
One will find this with all the manufactures.
Engine wise, the 5.9 uric had around a.dozen or so :-P options from 160-300 :-P. Two emergency service options to 360 hp or so. Some manufacture had low hp with higher torque options, and 20 or so hp/torque options, depending if you are powering a rig for giver, or for the.potential gcw it may.run down the.road. or if it will be.A.city.or hwy rig.
Way more to.This than medium, heavy.or.light.duty rated.
