The typical truck volumes for a standard Pick-Up are as follows:
Small Trucks (Ford Rangers, Chevy S10): 1 ½ yards level
6 foot bed: 2 cubic yards level
8 foot bed: 2 ½ cubic yards level
* Products such as stone and topsoil may alter carrying capacities due to weight.
Typically full sized trucks are able to hold 1 cubic yard of a heavier product like soil or stone, while smaller vehicles typically hold 1/2 cubic yard.
* Objects such as tool boxes and tonneau covers may alter truck volume capacities.
