Anyone have insight into combined weights for duallys?

I am looking for a tow rig and most literature limits the trailer to 10,000. Most constructions trailers weigh 6-7 empty so any equipment puts me over the DOT limit.

anyone have OEM literature on total capacities?

It varies greatly depending on the drivetrain, brakes, frame, suspension and so on. I had a 84 c30 dot rated for 14,500 gvw with a 8x12 flatbed I used to grab forklifts with. Bed was dock height and cut the forklifts up right on the bed.

Need to know powertrain detail, right down to the rear axle ratio.

Model year would help, too.

Update,

I spoke to the "heritage dept" of Gm and they confirmed even for a ~2000 3500 truck the max trailer weight is 10,000.

The 3500HD,~2002 is just 11,500.

I think these weights are more for the warranty aspect of the truck and not the capabilities. But 10K on a crew cab dually means the truck can hardly legally tow any piece of equipment. If i decent trailer weighs 4-6 only mini skid steer or excavator cold be towed.

He said there was no way to change/update the door sticker. This is a bummer because i wanted and square body to tow a cat 259d but the unit weighs 9k plus ~5K for a trailer. I know the truck can do it, just not legally.

Bumper pull or gooseneck/5th wheel type?

For example, my GMT800 truck is rated 12,000 with the platform hitch but 26,000 for gooseneck/5th wheel.

That might be a way to bump up your legal towing capability.

Where on your truck/sticker does it distinguish gooseneck/platform. I have never seen it split. I would like to pull a gooseneck tilt trailer. Most weigh ~8500 pounds push a skid steer of 9000. What is your max trailer weight?
