The trims that were left during this generation were the XL, XLT, and XLT Lariat. The engine options ranged from a 300 cubic inch inline 6 cylinder to a 460 cubic inch V8. There was also a 6.9L Diesel V8 engine.
The F-100 base model was finally dropped in 1983 and replace by the F-150, which is still in production today. Fuel injection became the standard for the base model by 1986.
This iteration of the F-Series lasted from 1980 until 1986. They are still fairly common on the used truck market, and they can fetch a decent price if in good condition. The larger engine versions are popular with farmers and ranchers who need that heavy duty strength. You can find quite a few listings on Ebay.
