An often overlooked, but very successful, family of models, the FLD series has proven adept at many tasks, and has proven itself to be dependable and robust, with many still in service over a decade after the last rolled off the line.
The FLD lineup includes the FLD112, FLD120, FLD120 Classic, and the FLD132 Classic XL. The numbers in the models stand for the BBC (bumper to back of cab) measurement. The 112 proved itself popular in LTL and other short distance rolls, the 120 was a popular long distance fleet truck, the 120 Classic was popular as both a sleeper truck and various vocational duties, and the 132 Classic was the "largecar" of the line, proving popular with Owner/Operators and fleets with an eye to style.
Built from 1987 to 2010, they were available with CAT, Cummins, and Detroit power, with various auto and manual transmission options.
Also available were several cab styles and sizes, from daycabs to the smallest 48" sleeper to the largest 70".
On the sleeper subject, at one point Freightliner designed and marketed a sleeper for the line that resembled the Peterbilt sleeper of the time so closely, Pete accused FL of copying their style, which apparently FL was guilty of, as they stopped production of said sleeper after a very short time (see photo of sleeper below).

I've personally spent time in a few FLDs, and have found them dependable and robust, standing up well to hard use and handling a variety of jobs.
Thanks for looking!
