The truck is a 06 2500HD Crewcab Silverado, when I was dropping off some scrap steel the other day it said my weight on the scale empty was 6,500. I haul everything from my jeep, skidsteers, mini excavators, dump trailers, concrete, trenchers, anything like that. I typically haul a trailer a couple times a month and the trailer and skidsteer combo I used weighed about 14,500. It does see dirt, Im out on different jobsites daily, some of them are hard packed dirt and others are mud. I also use my truck on some of the bigger trails at redbird or another place around here called the ranch for cleanup days for hauling trash, stone, drainage pipe and tools out to the trails. I currently have 285/75/16 Hankook MT's on there right now and like those tires they grab pretty well offroad they have just worn down quick.
