CCC confusion
Some clarification needed on CCC. Does this include the estimated weight of passengers?

Thanks, that was my thinking, BTW, we got rid of the Flamingos. ;)bukhrn wrote:
SCWR is confusing, do I count the sleeping positions=6, OR the sleeping positions "actually occupied" =2 ? :h
By definition, SCWR is based on the number of sleeping positions (6). Anything else is not SCWR, but some other weight. The intention of the required numbers is mainly just to provide some consistent comparisons between units.
In terms of loading your own RV, you of course only need to account for the actual weight of the people traveling. The chassis doesn't know or care if the load on the axle is from people or linens or George Foreman grills or plastic pink flamingos, so if you have fewer and/or smaller people, you can safely carry more stuff(and vice-versa).bukhrn wrote:

If you don't use them you will have more available ccc for other things.
If you're really concerned you should go to a scale. Fill all the tanks (fuel, propane, water etc) and load the passengers you would normally bring. Subtract that number from your gvwr and what you have left is your actual ccc remaining. The weight of everything you add to the rv, gear, food, clothes, more passengers etc shouldn't exceed that number. camp-n-family wrote:

. Here's how to calculate an RV's cargo carrying capacity:
Start with the vehicle's gross vehicle weight rating (GVWR)
20,000 pounds (GVWR)
Subtract the vehicle's unloaded vehicle weight (UVW)
The UVW is a manufacturer provided weight measurement of the vehicle that includes a full tank (or tanks) of fuel, coolant and oil
14,500 pounds (UVW)
Subtract the weight of the sleeping capacity weight rating (SCWR)
The SCWR is another manufacturer provided weight measurement (a maximum weight) determined by multiplying 154 pounds times the number of sleeping positions
924 pounds (SCWR) (6 sleeping positions x 154 pounds)
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. For safety's sake, the RV CCC should never be exceeded.- CCC is not a firmly defined thing. It was left open to interpretation my the manufacturers.
There is an official federal definition out there now which is known ac OCCC. (Occupant and Cargo Carrying Capacity. It is defined as how much people, water, and stuff you can put in an RV that is fully fueled (propane counts as fuel). It is MANDATED that this number is placarded in the RV. This new rule came about maybe 8 years ago. Once in a while the government does something right. - . Here's how to calculate an RV's cargo carrying capacity:

This might help:
CCC (Cargo Carrying Capacity), used Sept 2000 – present, means GVWR minus the following: UVW, full fresh (potable) water weight (including that for the water heater) full LP gas weight, and SCWR. Note: Remember that optional accessories or equipment not included in the UVW will take up part of the Cargo Carrying Capacity.
SCWR (Sleeping Capacity Weight Rating) is the manufacturer–designated number of sleeping positions multiplied by 154 lbs (70 kgs).
