I used Movaholics back in November to help load a moving truck before moving to Houston. Andy was very nice on the phone, the guys that loaded the truck were nice and the price was reasonable. They stacked all the boxes at the front of the truck and put my furniture up against the boxes to hold them in place. That seemed like a good strategy at the time, but when I unloaded the truck, the wall of boxes had collapsed and it became apparent that they had put some of the lightest boxes on the bottom and some of the heaviest at the top. The "wall of boxes" at the front of the truck was also unnecessary as the truck was not full. Andy requested that I rent moving blankets with the truck which mostly went unused. He said nothing about tie downs and it seems that their "wall of boxes" strategy requires them.
Bottom line: these guys are good if you're looking for help unloading or loading for a local move, but I cannot recommend them for loading a truck for a long move.
