89 Chevy 3500 Dually question

Texas Red · May 17, 2018

Just picked one up from a friend for a song. Has a 454 TBI, 3-speed manual w/granny gear and a 4.11 rear axle [2wd]. Tire size is 235/85 R 16. The door sticker is toast and I was wondering if anyone knows the maximum towing capacity of the truck? I've searched all over the web and can't find a definitive source for the info. If anyone knows of a specific site where I can find it, please let me know.

Thanks, Kelly

Proably in the low teens. Maybe 13000 pounds. Could even be 10,000 pounds. Hard to know without knowing the rest of the trucks options.

It's got huge helpers on it, power steering, power disc brakes, trailer package with dealer bumper hutch, Gooseneck in bed, 2 bumper hitches in back [really big double decker 3/8" steel plate one]. I am really after the maximum factory number so I can add in the gooseneck and helpers on my own to come up with a maximum. No other load based options on the truck.
