heavy metal...
My 74 K20 I no longer have used to weigh in at 6,280 lbs with the flatbed and crane setup on it,with not much gas in it,empty!..(including me at the wheel,I weigh 170 lbs.It had a plow frame too--with the 8'plow on it was well over 7000 lbs..I weighed in at 12,570 lbs once when I brought a detroit deisel straight 6 motor from an old bulldozer to the scrap place once..

--still cant believe it didn't snap the rotted frame in two!..
My 82 K20 weighed in at 5450 lbs empty,with a nearly empty tank--it has a plow frame,a 6.2 deisel,and an 8' stepside bed!..weighs less than I thought..its about 6000 with the 7.5 ' plow on it..
The "lightweight" of the 3 is my 79 C10,with an 8' fleetside bed --It used to weigh 4800 lbs with the 250 six it had--now with a 305 and a few other things like tools in the cab it weighs 4950...all these readings were on a digital scale used at the scrapyard to weigh big rigs,it might not be 100% accurate,but I bet they are very close..
I weighed a frame I cut up and junked a week ago on an old bathroom scale,it said 500 lbs,and they paid me for 520 lbs,I also had a catalitic converter and some other light stuff,so I think their scales are prettty accurate..
