Just watch a very cool setup. Neighbor had a portable storage building sitting in the driveway, and the man just arrived to pick it up. Flatbed truck, carrying a mobile lifting rig. Looks like I-beam structure, powered and on its own wheels. It can widen-narrow, all four wheeled legs lift and lower independantly. Lower them and drive it off the truck, adjust size and move it over the storage pod. Lower, hook up, then lift the pod. Back the truck under it, center it & set it down, the close the rig up to the sides of the bed, lift the legs up for clearance, lock it all down and drive away.
Someone did a find job designing this setup, and I hope they get rich with it.
