Iodoform gauze is a type of sterile, absorbent fabric used to pack wounds and facilitate blood clotting and general healing. In most cases it is materially identical to standard medical gauze except that it has been treated with or soaked in iodoform, an antiseptic.
GCWR takes into account GVWR and loaded trailer weight. The GCWR is the maximum weight the vehicle can carry and pull together. The loaded trailer weight plus the GVWR of the vehicle cannot exceed the GCWR as specified by the manufacturer.
The gross vehicle weight rating (GVWR) is assigned by the vehicle manufacturer or finisher. Please note that the GVWR on your DMV paperwork may not be accurate, and should not be reported. The GVWR required for the regulation represents the maximum weight of the vehicle and what it can carry when fully loaded.
