Will my 84' K5 Blazer 1/2 ton 4x4 350/TH350/3.73:1/32" tires tow a 56 GMC farm truck(4,980 lbs) on a trailer (~1000 lbs)? What is the rated towing capacity? I will be towing it over a couple of mountains between San Francisco and S. Oregon. Thanks, Nate Attachments: https://talk.classicparts.com/images/attachments/409129350584a09a.html
multiply the engines rated horsepower by 35 and subtract the weight of the truck passengers and cargo. The result is the approximate ideal maximum weight you should tow, although a numerically higher axle ratio can help compensate for heavier weight.
