its a liability thing really. I worked at one in Florida and I remember having people sign off on tiles, concrete, and blocks.... You'll be surprised what some folks throw in there trucks.... ( full pallet of quickcrete ) ... Scary when ur lowering the forklift in the back of the truck and wondering when its gonna stop squating.... I laughed and always asked when they wanted to drive off... Are leafsprings supposed to be U shaped or opposite? Not many folks knew.

 

yeah my old 1/2 chevy had 1-ton springs and bags under it. took me 15 min to convince the forklift driver to put a full pallet of driveway pavers in the bed.
