I'm trying to figure out the ratings for the 08' crew cab 4x4 dually. The literature does not give a weight rating of the vehicle, but what I've found in the internet seems to be an empty weight of roughly 6,700. The GVWR is 11,400 so that leaves 4700 for payload, people and misc. items? The trucks payload rating is 4706 so if you max the payload how can someone then get in with some misc. tools and a friend and drive it legally? Also, what is the GCWR. I can't really find that either. I'm guessing 15,900. So that would leave 6700 for vehicle, 4700 max payload, 700 pounds (two people, misc. stuff) and 3,800 trailering weight? I might seem crazy with these numbers, but could someone clarify for me. I'm going to be carrying a Truck Camper that weighs around 4,100, pulling a boat that weighs around 4,100 and carrying another 1,000 of misc. weight. Thanks in advance for the responses!
