Justin Johnson put 62,000 miles on his pickup last year driving from one top-notch radiant installation to another.

With a customer territory of about 40,000 square miles, and an imposing mountain range that slices diagonally through it, roads aren't exactly arranged in a grid. As a result, the miles add up quickly in this part of the country. A straight line from point A to B might be only 50 miles on a map, but actually driving there can easily add 200 miles or more to the odometer. Johnson put 62,000 miles on his Dodge diesel pickup last year while moving between jobsites maneuvering through the Teton Mountain region.
