Long known for their big highway tractors, Peterbilt (part of Pacific Car and Foundry along with Kenworth) has expanded its range to include a range of vocational, and smaller straight trucks of all sorts.
Just by chance I have seen a couple of stylish straight Petes recently.
A nice change from the usual vanilla (like the generic lease Freightliner next to it) this Pete tandem with reefer body is probably a fish carrier. Its large fuel tank suggests long fast runs to the markets.
This Pete is operated by a company that makes automated medication dispensing systems. Based in Longueil, QC the company manufactures, delivers and installs its equipment throughout North America. The equipment certainly travels in style.
