The long haul stuff should go on rails anyway. It's very wasteful to run it on the interstates. The majority of the fatigue damage to the highways comes from trucks, then there's all the rubber dust, fuel inefficiency, etc.
The trailers should just be picked up and dropped on flatcars, and trucks used for intracity last mile stuff.
