I think the ones around here have it figured out.... find a rusted out, broken down trailer with at least one crack in the frame and a pickup to match. Stack that 8'x16' trailer with pallets 8'x20' and at least 14' high and secure it all with one piece of 1/8" rope. Ensure the cracked trailer frame makes the pallets lean into the oncoming lane. Stack the pickup just as high and use another piece of 1/8" rope with several splices in it for added strength. Also it should be a 1/4 ton truck with only about 1/8 ton worth of actual load capacity left in its suspension so it gets the proper ride at the hitch... you can tell it is a proper ride because the one safety chain is dragging on the ground.
I am pretty sure that they make their equipment investment back on the first load
