Headed out tomorrow with new Class C Thor Four Winds 31F - Ford E450. Can't figure out if the CCC on the door (1649) includes full water, propane, driver and passengers? Conflicting information online. We have house seatbelts for 7 plus the driver and driver passenger seat for a total of 9 seats

.

Don't want to overload, but how does Thor calculate the CCC? GVWR is 14500 and shipping weight is 12466 (does that included full gas?). Any help would be greatly appreciated

I'm no expert, but generally it does not. I think the driver & a full tank of gas is pretty much it and everything else must be added to the weight. Passengers, gear, food, bedding, water, clothing, toiletries, pets, their food, their gear EVERYTHING.

Here's a link that might help: Understanding Motorhome Weights | RVSEF

I suggest you load RV and take to local truck scales. Get it weighed by front and rear axles at the very least, best would be a '4 corner' weight but many scales can't do that. Pay attention to the axle and tire capacities before heading down the road.

Unfortunately, the weight stickers are seldom accurate. It will help to have a 4 corner weighing, so you can have an enjoyable trip. Adjust tire pressure, loading, etc accordingly.

TMC is a RVIA compliant mfgt. The CCC (should actually be OCCC for motorized RV) is GVWR minus UVW and full propane tank.

So, if the orange/yellow sticker on door jam says 1649, that is the driver, the passengers, all their stuff, the amount of water carried (fresh and waste), the fuel carried and any weight placed on the hitch receiver like a bike rack or tongue weight of a trailer.

These numbers can be calculated to avoid overload, but just takes the effort.
Water is 8.3LB/Gal
Gasoline is 5.6LB/Gal

These calculations can include a decision like to fill the water at home or at a destination...and this will (slightly) impact MPG too.

Yes, it is very possible to overload a RV and the OP is smart to think about this

Unfortunately it appears that the manufacturers are allowed to produce their own, onboard weight stickers , so the actual weight calculation , is still up in the air.

In the VERY fine print, of my Newmar sticker, it states " vehicle weight with a full tank of fuel" does not include " driver or passengers, fresh or waste water, LP or any other cargo." CCC 3,345 lbs.
To erase all doubt, looks like scale weight is the only option.

If it's 2008 or newer it should say "OCCC =x,xxx lbs"

What you need to know is OCCC has already accounted for full fuel tanks (both LP and motor fuel). That 1,649lbs number is every person, cargo, food, hitch weight, and drop of water you add to the motorhome.

Don't forget about the water in your 6 gallon WH. That's 50lbs right there as only the WH empty is included in the UVW (shipping weight as you said).

Our 2011 Sunseeker 3170DS weighed in at 14,300lbs on our last 10 day trip. We are a family of 5 and had our 2 large (95lbs&75lbs) dogs with us. However, our unit looks to be 500lbs lighter than yours.

The number of seat belts is no indication of how many people you can carry without being over loaded. They are located so the "few" people you are carrying can sit where they want comfortably and safely.

most times its only gas in manuf # all else is on u mine said gas only & its a 98. if u know where u will be at nite just carry enough water to flush & little at sink . I never carry more then 10gal unless going to dry camp
don't understand your # 14.5 -12.4 is abt 2000 not 1600

The definitions changed in 2008. According to RVSEF (The Recreation Vehicle Safety & Education Foundation) The RVIA (Recreation Vehicle Industry Association) has revised definitions a couple of times. In 1996 UVW (unloaded vehicle weight) was, "The WEIGHT of a vehicle as built at the factory with full fuel, engine(generator) oil and coolants. It does not include cargo, fresh water, LP gas, occupants, or dealer installed accessories."

NCC: Net Carrying Capacity was (1996 RVIA Definition) The MAXIMUM WEIGHT of all personal belongings, food, fresh water, LP gas, tools, dealer installed accessories, etc., that can be carried by the RV

In 2008 RVIA defined CCC only for trailerable RVs. "Equal to GVWR minus UVW and full LP gas weight" and OCCC (Occupant and Cargo Carrying Capacity) "Equal to GVWR minus UVW and full LP gas weight." So, the passengers, their gear, food, water, etc.

LP weighs 4.2 lbs. per gallon. Gas 5.6 lbs. per g., Diesel 6.8 and Water 8.4.

Some of the above posts are using their older RV labels, to make points in a question about a "new Class C Thor Four Winds 31F" just be aware things changed in '96 and '08 so some of the terms have changed.

Note: the OP's RV shouldn't have a CCC label since its not a trailer. It should be an OCCC sticker.
