Don't get in a hurry, and you can get in to a nice truck for 1/2 to 1/3 the price of a new 1 ton dually. I lurked here for a while, asked some questions, and found a '01 Volvo 770 for $19.5k, with auto shift and 700k miles. So far we put about $5k in to the bed and air hitch, and another $1500 in repairs.
Or, do as I wish I'd done, and buy one already built and tested from some one here who's moving in some other direction.
