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.
Note: The tow vehicle and RV each have a GVWR. GAWR (Gross Axle Weight Rating) is the maximum allowable weight each axle assembly is designed to carry, as measured at the tires, including the weight of the axle assembly itself. The GAWR is specified by the vehicle manufacturer.
