been pulling a fifth over 18000 with a full bed and some on the rack above the cab as well as well for three years now. Everything stock except for the 19.5's and tires. Only pulled about 10,000 miles so far but not a problem. rear is a 4.11. Do plan on upgrading the tranny + if they ever go south. one of these days we gonna get brave and weigh it
