Awesome find. If nothing else on the washers and dryers I would at least also remove the wiring harness, you can generally get close to a dollar a lb for insulated #2 wire. It sounds like you would anyway, but make sure you treat everyone there with respect, dress in clean clothes and follow up and keep any schedule you make with them. This will really make an impression with them and will probably turn into a continual permanent supply, and they will let anyone in their same business know about you if that other person needs some stuff hauled off, especially if it does not cost them anything and therefore will not hurt their bottom line.
