Default OCCC and CCC

I thought I'd try to give a very short description of what OCCC and CCC label info means. Please let me know if these discriptions miss anything and I will update them.

Occupant and Cargo Carrying Capacity = OCCC
Unloaded Vehicle Weight = UVW
Gross Vehicle Weight Rating = GVWR

OCCC = GVWR minus (UVW + weight of full load of propane and propane tanks)

Water is now part of your cargo (8.3 lbs per gallon) so it needs to be subtracted from OCCC.

Basically subtract occupants, onboard water and clothing, food & gear etc. from OCCC to make sure you're not overloaded.

Note: CCC superseded by OCCC since mid 2008

Cargo Carrying Capacity = CCC
Unloaded Vehicle Weight = UVW (or ULW)
Sleeping Capacity Weight Rating = SCWR

CCC = GVWR minus (UVW + weight of full load of propane + full capacity of fresh water including the water heater + SCWR).

Basically subtract clothing, food & gear etc. from CCC to make sure you're not overloaded. You could add back some of the capacity lost to SCWR if there are less occupants in the RV than the SCWR allowed for.

I suggest a trip to a weigh scale with your van fully loaded to get the actual weight of your rig.
You could post your results here:

Example (my van):
GVWR is 9,500 lbs minus 8820 lbs = 680 lbs under.
8,820 lbs at the weigh scale included all of my gear on-board, driver and passenger, full water tanks, full cargo box and bikes on the hitch, some food in cupboard and fridge. Coleman stove, propane bottles, BBQ, screen room, 2 chairs plus 2 lounge chairs, tools, 3/4 full diesel tank and 3/4 full propane tank, pots, pans, plates, utensils etc.
