I can attest to that dairy delivery job! I worked for six weeks as a temporary delivery driver for a western Colorado dairy. There were two routes that were each run twice a week. Both routes covered approximately 225 - 250 miles, and I drove an International Harvester 5100 reefer truck (single rear axle) with a seven liter Diesel, 5-speed manual and two speed Eaton rear. A bear of a truck! This was all mountain driving, so that mileage and the stops was an all-day event. Load the truck, starting at 0400, hit the road at 0530, and wrap things up by 1800 that afternoon. All stops were at restaurants and retail stores. The scary part was the roads! I had more than one time, where the rear axle would not engage from Lo to Hi, or vice versa, and I'd end up coasting down a two-lane mountain highway until the rear would engage! Scary times there, I tell ya! The money was great for the late '70s, and I actually came to like the job, but the guy I was subbing for was recovering from surgery, so it was his route to start. I was happy to let him have it back.
