Moving companies such as U-Haul often offer various sizes of trailers for rent. Some local car companies might also offer trailers as well, although most major brands only focus on car rentals.
People often use trailers for moving items long distances. While many people rent trucks and other vehicles that include a cabin, people with trucks or other vehicles that can haul a trailer can save money by renting a trailer. U-Haul and other companies also let people drop trailers off in different cities, although many charge extra for this service. Local car rental companies, on the other hand, might only rent trailers for local use.
