I think some shippers do this, have a small truck bring stuff to a big depot to be put on a truck. I sold a crane machine to a guy up north one time. A small covered truck came and got the machine, then drove it down to Florida to a depot. Then it came back up the coast on a big truck and finally to its destination. Regardless, the shipping company should disclose all this especially if you are paying for a covered blanket wrapped shipment.
