capability, opening a facility in Madison, Tennessee (suburban Nashville). Along with the ability to meet additional product demand, the location was chosen to serve customers closer to the East Coast. As part of a revision to the cab design, the 282/352 COE adopted the name "Pacemaker". 1970s In 1970, the Model 348 was introduced, gradually replacing the 341 (remaining until 1972). Intended for vocational use, the 348 was the first Peterbilt designed with an angled fiberglass hood; the 349 was similar in configuration, designed with a larger grille. Developed in a joint venture with Kenworth, Peterbilt released the CB300, a low-cab COE developed nearly exclusively for refuse transport. At the beginning of 1972, Pacific Car and Foundry, intending to exit steel manufacturing, introduced its current name, PACCAR. The same year, Peterbilt redesigned the cab for its conventionals, replacing the "Unilite" cab with the "1100-series" cab. Named for 1100 square inches of windshield glass, the new design was taller with redesigned doors, an all-new interior, and increased window space. Designed for the same applications for the slightly larger 383, the Model 346 6x6 was designed with a set-back front axle (placed nearly below the cab). For testing, the company developed a prototype vehicle powered by a jet-turbine engine; the design was not placed into production. In 1973, the Model 353 was introduced as a construction-oriented variant of the 359 (using its wider grille), replacing the 341 and heavy-duty versions of the 351; production of the Madison facility was doubled, allowing the company to deliver 8,000 vehicles yearly. In 1974, a set-back front axle was added to the 359. In 1975, Peterbilt expanded its manufacturing base a second time, introducing Peterbilt Canada in Sainte-Thérèse, Quebec (Greater Montreal).; the facility began production of the CB300 (sold by Kenworth as the Hustler). Sized between the 353 and the 383, the 387 was another heavy-duty truck developed primarily for off-road use. The 352 COE underwent a model revision, becoming the 352H (high-mounted cab) to accommodate larger engines. After a 22-year model run, the 281/351 was retired for 1976. Replaced by the 358 and 359 as the Peterbilt highway tractor over a decade earlier, the 351 had continued production as a heavy-duty truck built primarily for vocational use; in the early 1970s, its cycle-style fenders were replaced by flat steel fenders. The narrow-hood 358 was also retired, as the larger-grille 359 was better suited to the
