78 K20 7500 GVWR Tow Rating?
« on: August 14, 2007, 12:44:03 am »
Might be silly, but what is a 1978 7500 GVWR K20 rated to tow?  4wd, 4 spd, 4.10 gearing, 350, etc...I know some can be different depending on various combinations.
Mucho appreciated!

Not sure an actual lbs. I have towed stuff over 10,000lbs on a trailer with brakes behind several of my 3/4 tons.
