Base Curb Weight, GVW, GVWR, Tongue Weight.  What does it all mean?

Base Curb Weight This is the weight of the vehicle including fluids (fuel, coolant, lubricants) and any standard equipment installed by the factory.  It does not include passengers, cargo, dealer or aftermarket installed equipment. (see UVWR)
Gross Vehicle Weight 

(GVW)

This is base curb weight plus passengers, cargo, dealer or aftermarket installed equipment.  GVW is not a limit or specification, it is merely the weight of your vehicle at a given point in time. Note, when a trailer is attached this weight would be PLUS the tongue weight.
Gross Vehicle Weight Rating

(GVWR)

This is the maximum total weight the vehicle was designed to carry.

Gross Axle Weight Rating

(GAWR)

This is the carrying capacity for each axle system (this would include the tires, suspension components and the axle).  You will usually find that the rear axle has a higher GAWR than the front.  Do NOT make the mistake of adding your 2 GAWR and thinking that this is what your vehicle will carry.  See GVWR, which will usually be lower than the sum of the 2 GAWR.
Gross Combined Weight Rating

(GCWR)

This is the maximum combined weight of both the towing vehicle (including cargo & passengers) as well as the trailer (including all trailer cargo)
Maximum Trailer Weight The maximum weight of a trailer the loaded vehicle is permitted to tow.  Subtract the weight of the loaded vehicle from the GCWR
Gross Trailer Weight

(GTW)

Weight of Trailer Fully Loaded
 
Tongue Weight

(TW)

The downward force, or weight exerted by trailer coupler on hitch ball
Unloaded Vehicle Weight Rating

(UVWR)

This is the weight of the vehicle (usually a trailer) including fluids (fuel, coolant, lubricants) and any standard equipment installed by the factory.  It does not include passengers, cargo, dealer or aftermarket installed equipment. (see Base Curb Weight)
Unloaded Tongue Weight The downward force, or weight exerted by trailer coupler on hitch ball of an unloaded trailer including any standard equipment installed by the factory.  It does not include cargo, dealer or aftermarket installed equipment.
Cargo Carrying Capacity

(CCC)

This is the weight of cargo, dealer or aftermarket installed equipment you can carry. Subtract UVRW from GVWR to determine CCC
