it would be fun to do if i was retired, and needed something to keep me busy.

but from what i understand, you HAVE to take everything from the unit (not a big deal if u can jsut take most of it to a dump)
i think it would be fun, but its a risk(always) and if u see something good, chances are others have also, and you will pay for it.

i guess having time,resources(truck,storage, places and sites to sell items) and a sharp eyesight is all it comes down to.
