The Ford F-Series is a series of light-duty trucks marketed and manufactured by Ford since the 1948 model year. Slotted above the Ford Ranger in the Ford truck model range, the F-Series is marketed as a range of full-sized pickup trucks. The most popular version of the model line is the F-150 pickup truck, currently in its 14th generation. There are many reasons why the Ford F-150 is the best truck on the market. For one, it has a strong and durable frame that can withstand a lot of wear and tear. Additionally, the F-150 has a powerful engine that can tow heavy loads with ease.
