Regular made officially permanent / what to do with this stuff?

I had a regular (had them for 1.5 years now) contact me again yesterday - one less than 5 miles from my house and their "higher ups" made it official that I am the person they contact for removing their metal and similar materials etc in all their warehouses... They are fine with the fact that I work full time and am only available on weekends or after hours.



I picked up these from them last night and am trying to decide if I should attempt to dismantle these GIGANTIC transformers for the copper or just sell them as is? I say "GIGANTIC" because with just 2 cabinets (2 large transformers per cabinet with a bunch of small ones in each - insulated copper and capacitors etc..), my truck is sagging and two of us could hardly load the cabinets on the truck, in fact they were strapped to a pallet so they could forklift them into my truck. Should I bother trying to cut them open to take out the copper or just sell the transformers as they are - without the screws and wire etc...?
