UPS trucks, or “package cars” as they are referred to by the brand, have been built by a variety of manufacturers over the company’s history. The body is custom-built by different coachbuilding firms including Union City Body, Utilimaster and Morgan Olson. While, in previous decades, their chassis came from Ford or GM, modern vehicles use a Freightliner or Workhorse chassis. Have you ever driven a delivery truck or other commercial vehicle?
