There are no foolish questions on this site, unless you ask: "can you make any money expediting?"
Usually, a carrier defines a Truck and it's cargo carrying capacity as A, B, C, D, and E
A = pickup or mini-van with a capacity of one cube (4' x 4' x 4') or 500 pounds or less.
B = Cargo Van capable of carrying two cubes, not exceeding 2500 pounds.
C = Small straight truck with a cargo capacity of 5000 ponds and be dock high.
D = Large dock high straight truck with a capacity of 13,000 pounds
E = Tandem axle tractor with a cargo capacity of 44,000 pounds.
Example: One pallet weighing 1000 pounds would be a B load.
