So 5,153 - 4,600 = 553#?? That's rather dissappointing. Of course, that does not include the added weight of the larger tires, DIY beadlicks, Iron Pig skid plate, winch, tools and parts, etc. I'll weigh my 80 when I get back home for a better guess at the total weight loss. Still, it's a full 1,000# lighter than my fj40
