You want to make sure that the truck its load on is the truck making the delivery. A lot of times a local crew will come and pick up your stuff only to take it to a warehouse unload it and a another drive will load it then deliver it to you or possible to another warehouse local crew who will deliver it to you. No matter what you decide over kill on the packing a must. Make sure every box you shipped is on their inventory. They're are good moving companies and bad moving companies. It all comes down to the driver and his helpers.
Good Luck
