There are thousands of boxes in Chicago available for purchase. Obviously you find them at ports, unless some enterprising individual has hauled them out to bugtussle.
You've heard of Ryder, Uhaul etc . Rent real moving trucks.
M1022 is a nice piece of equipment but rated load is only 15000lb. that's your box PLUS the load. Empty (tare) weight of a 40' box is 6850# or a 20' is 4190#. The M1022 is 5580#, 198.5" long + the box. Mil rates the M1022 for a 5t. They do pull very nicely. Full air brakes.
