GVWR (Gross Vehicle Weight Rating) I believe is JUST the weight of the vehicle. "Add-ons" are just that, things that are added on and, don't count towards the GVWR. The GVWR is established by the vehicle manufacturer who puts a legal placard on said vehicle. If the vehicle is REmanufactured, the remanufacturer may (must?) re-placard as appropriate. The CVWR (Combined Vehicle Weight Rating) is the maximum weight a vehicle cannot legally exceed and, that included trailers (and I guess whatever else someone decides to add). On my Super-C Dynamax, the GVWR is 33,000 pounds. The CVWR is 54,000 pounds. You would think I could tow 21,000 pounds BUT, the tow hitch Dynamax installed is rated at 20,000 pounds so, I "lose" 1,000 pounds of tow capacity (but, that "lost" 1,000 pounds increases my safety factor).
quick question: does the king pin weight add to the gross vehicle weight or is the gross vehicle weight only the max fully loaded vehicle without the trailer? i have to declare a max vehicle weight while registering and am not sure about that part.
thanks a lot
