1981 GMC K20 3/4 ton 4x4... 500 bucks.. ya ya ya 499 to much.. It has a 350 motor, 350 auto trans..
I use my trucks for hauling fire wood and tractors.. This may not tug my tractor around so well.. but it will be good for fire wood..And they were made to last back then, just like your tractors!
I like the camper top: that's worth a good chunk of what you paid for the truck. Plus the 4wd: never call a truck a hauler unless it is 4wd or a dually!
Most trucks in my area of that vintage have already been lassoed by the farm boys and used as beater trucks or oversize ATV's. But I'm still looking!
