Mine is geared with 4.10's and a e40d. And if i remember right it says the gear ratio on the door jam or gives a code for it. And the axle should have a tag on one of the cover bolts if it is still there and legable it will say. Just cause you can do it doesn't mean you should tho. I feel as if im experienced enough to do it and a good trailer that is properly loaded and trailer brakes are a biggie. Also a truck that is not designed to do it will not live forever doing it.
They are pretty burly trucks, I wouldn't be afraid to hook 10,000 lbs behind mine and go anywhere, mine is a 96 5spd 410 gears, On occasion I would say what ever you need to pull, make sure your tires and brakes are good.
