Topsoil, mulch, gravel by the yard. I think by the weight would work for all of those, and firewood, but then how would the government stick their nose in it. You do need a standard. I remember one young lady was almost at tears because I was giving her too much wood. She had used a local supplier for several years. She waited till Christmas eave to call us. She was surprised I was cheaper than her guy, and then when I got there, and told her all the wood on the dump truck was hers, she started freaking. She couldn't fit it, and her car, in the garage. She wasn't allowed to stack it out side, homeowner asses. She was happy and didn't know the scumbag was ripping her off. To a young homeowner that has never heated with wood, a cord is a giant pile. It's wan't right he ripped her off just because she didn't know. He could have taken that same load and said "this load, this much" and she would have been happy, and he still would have been ripping her off.
