as far as I can tell, too much freight is already a problem. instead of taking on the amount of freight that can be safely handled in a timely manner, ConWay has tried to pack in as much as possible in a day for $$. that's why we need the safe stack system. more more more! that's why most days I'm overweight and stuff is stacked on top of each other to where I have a time getting it moved or off the trailer and can't get all of my stops done before places are closed. happened twice last week. it's not every day, but it's too often.
