    So I think I know what the gross combined vehicle weight rating is, it is the max combined weight of the truck, trailer, cargo, driver, fuel and other contents. Is this correct?

    Why I ask is i came across a truck for sale that has a GCWR of 73,500 LBS and I don’t get why it’s so low. Its an old White/Volvo day cab cabover, tandem axle, single screw with a 60 series in it. I figure the manufacturer sets this rating based on safety/engineering limits but why is this so low on this particular truck? Does it have to do with its cab or “body” weighing less than say anything with a sleeper or even a conventional day cab or is there less frame than in a conventional day cab?

    Has more to do with axle rating than frame or body.
    A typical drive and trailer axle is rated at 20k lbs. So a single screw with a 2 axle trailer would be 60k lbs. That leaves 13,500 lbs for the steer axle, which is a common steer axle rating.
