Few things are as American as pickup trucks. Most trucks sold in the United States fall into the category of small trucks (usually based on cars and often called "crucks"), midsized pickup trucks, and full-sized pickups. Pickup trucks are defined as having a passenger compartment and a separate utility bed for hauling cargo. Most Americans also include a body-on-frame style of construction as part of their definition of a pickup truck.
The bed of a pickup can be box-shaped, a flatbed, a work bed, or any of several options. Most pickup trucks are sold with an open box-style bed with a flat floor and low sides and a tailgate. Full-sized pickup trucks are also categorized by a now mostly traditional suspension rating, being divided generally into half-ton (1500 ), three-quarter ton (2500), and one ton (3500) or, alternatively, light-duty, medium-duty, and heavy-duty. The actual weight the truck can carry now longer has any relation to these numbers and these numbers can now get far higher (4500 and more).
Popular pickup trucks in the American market include the full-sized Ford F-series, the General Motors series of GMC and Chevrolet trucks, the Dodge and Ram Truck series, the Toyota Tundra and the Nissan Titan. Popular midsize trucks include the Nissan Frontier, the Toyota Tacoma, and various midsized trucks that are now largely discontinued from GM, Ford, and Dodge.
The Ford F-series includes the best-selling pickup truck model in the United States, the Ford F-150 half-ton, as well as the other F-series trucks. The numbers after the F indicate the truck's suspension capacity divided by ten (e.g. F-250 when introduced had 2,500 pounds capacity). The Ford line has been popular as a working man's "everyday" truck.
The Chevrolet series of trucks have changed their names over the years, but the current moniker is Silverado, often followed by a class rating (1500, 2500, etc). These are well-known in the market for their strength and many buyers are loyal to the GMC and Chevrolet nameplates.
The Dodge nameplate was replaced by the Ram Truck name, with several offerings in the truck market usually designated simply by their weight rating. So the Ram 1500 is the half-ton full-sized Ram Truck offering. The Ram series is popular as the only full-sized pickup truck in America with a coil spring rear suspension system, making for a more comfortable highway ride when not under load.
The Toyota Tundra is a full-sized truck in the half-ton market with a reputation for being dependable and hard-working and whose sales figures have grown steadily since its introduction. Toyota's midsize truck, the Tacoma, is the best-selling small pickup truck in the market.
The Nissan Titan is a full-sized truck recently introduced by the automaker to compete with the Tundra and Detroit makes. It has grown a steady, though still small, market share and sells largely to those who prefer a truck with a more unique look and a well-trimmed interior. The Nissan Frontier midsize pickup has been sold on the American market for some time and is popular as an outdoorsman's machine with good offroad capability and strong appeal to a younger buyer.
