After nearly four decades, the Mack RD, the last of the R series models, is being retired at the end of 2003. To celebrate, Mack is offering a special edition of the vehicle, called the R-Model Legend.

More R-model chassis have been built and registered than any other Class 8 vocational vehicle in trucking history, according to Mack. Approximately 360,000 have been produced since 1965, and more than 200,000 are still operating.

"The RD was a real workhorse - truly Bulldog-tough - and helped forge our reputation for dependability and durability. So we want to send it out with a bang," said Tom Kelly, Mack's marketing vice president.

The R-Model Legend is tricked out with limited edition paint, badges, chrome, a special steering wheel and embroidered seats. Production will be limited.
