This is how it works: GVW 5000 lbs (c10) - the weight of the truck with driver and fuel = Payload
5000lbs-3500lbs= 1500 lbs net payload

C20 gvw 7800lbs (ones without a full floating hub) 7800 - 4500 = 2300lb net payload

C20 8500gvw - 4900lbs = 3600lbs

C30 dual rear wheel 10,000lbs -6000lbs = 4000lbs net payload

next class GCWR gross combined weight rating

I own a class 8 truck dealership and I do know trucks all the way up to heavy haul stuff that moves 500,000 lbs....

each rating requires changes in tires, spring, brakes, frame, driveline, clutch, overall gear rario in rear axle and transmission.....

You may be able to get it to set level but u will have a hard time stopping it. Get a heavy 3/4 ton and save yourself a lot of trouble. Kieth ps no hostility intended.....good luck
