Ford trucks are among the most popular worldwide, and with good reason. They are generally a reliable and durable choice. However, there have been a few off years for the Ford F-150. If you’re in the market for a used pickup, there are three years you should avoid.

By the same token, three F-150s model years offer a redemptive value that Ford fans have come to expect. Let’s take a look at the particular specs that make each year notable.
