I'd consider hauling it in the way it is if you're near a shredder. Pistone mentioned earlier in the thread, .15-.18 cents per pound, it adds up quick.
If you want to cut it up, I'd say the quickest way would be a plazma cutter. The other thing I would think of is put a add on CL and sell it to some one who is set up to handle the trailer. Collect their money, plus the $2,000 from the owner.
