Weigh scales, too. Usually their scales are just large enough to get all wheels on it. My 72 is 4000-4100lb, without me in it, quarter to half tank of gas, spare tire, rear bumper, no a/c, power steering, with toolbox, and maybe 50 pounds of misc crap in it. According to the scale at the junk/scrapyard I used to work at, so god knows how that scale could have been rigged.
Not as bad as my 97, with gear and tools, it drives everyday at about or a bit above the 6,000lb mark. half ton truck.
