Subtract the weight of the propane fuel (LP gas) Propane weighs 4.2 pounds per gallon; 50.4 pounds (LP gas) (12 gallons x 4.2 pounds) Subtract the weight of the fresh water on board; Water weighs 8.3 pounds per gallon; 207.5 pounds (fresh water) (25 gallons x 8.3 pounds) The result is the cargo carrying capacity (CCC) of the vehicle 4,318.1 pounds (CCC) (cargo carrying capacity) It's important to understand that the cargo carrying capacity definition, as outlined for you here, is a weight limit, or maximum weight, as determined by the vehicle's manufacturer.
A cubic centimeter (cc) is volume which is a measure of the displacement of the engine. 1000 cc = one liter. so a 1500 cc engine is the equivalent displacement of a 1.5 liter engine. cc's are generally used for small model engines (just a few cc's) and motorcycles (10's of CCs to 1000 or more) and small cars (up to about 2000 cc).
