Unique tractor turning method - GIF

I have compared the fuel consumption reports of my bud's truck since we installed the 18 speed compared to when it had the 10 speed his fuel mileage per gallon consumed went up an astounding 20% over a 150,000 mile summery.
the 17 year old truck with 950,000 miles on it still shows a lower cost per mile than the newer 2018 trucks running a similar amount of HP but with automatic transmissions can obtain. even if you consider those trucks as being paid for like his is.

Soon [as if not busy enough] it'll be time to exercise wallet moths IYKWIM. Ain't no trucker but have what should be advantageous in my operation; occasional OTW to haul back machine & material finds, and local for construction materials to complete the building. 20' flatbed 1979 F8000, CAT3208 non-turbo, Fuller 13, tandem differential, 4 duals, 52k GVW. It was a transit mixer, then a construction [tilt] flatbed still. Bought from local construction yard. Looks like hell but drives very nicely. Being I can't have a fleet of trucks, this and a low-boy forklift trailer should do pretty well.
I wish the 'Trick My Truck' reality program was still operating, would be a great candidate. But all those were tractor/ sleepers.
Later year, no visible differences, other than stake pockets. Even the same wheels, with mixer sized rubber. And this lists 3x more $ with higher road miles.
