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 maximum load for which the trailer is designed is called the GROSS VEHICLE WEIGHT RATING (GVWR). This is the total of the weight on the axles and weight on the trailer tongue or fifth wheel kingpin. The maximum trailer weight a specific axle is designed to carry is the GROSS AXLE WEIGHT RATING (GAWR).
