Grumman Olson with Cummins 4BT mileage report

[66788]

I have just finished 3 round trips from Sacramento, CA to Oregon carrying personal items in my Grumman Olson step van which as a 3.9 L  4 cylinder turbo charged Cummins 4BT diesel motor.   The van is a GMC chassis, 1990, with a rock crusher 4 speed transmission.  It has a governor, so the top speed is 60 mph.   The ceiling is over 7 feet high, and the usable area from the rear of the front seat to the back is 16 feet.   The distance was obtained using a Garmin GPS, not the vehicle's speedometer.   All trips produced the same mileage, so I believe it to be very accurate.

Empty van: 18 mpg.
Loaded with 2,800 pounds of cargo: 15.5 to 16 mpg.

That's not bad for pushing a 10,000 pound box down the road through mountains on I-5.

I am hoping for completion of the build by September.   We'll see!

High probability!   Has the date and time been set already?
