Take the 3460 from the thread above and subtract 760 pounds for engine (272=625#), transmission and associated gear/fluids then subtract 200 pounds for the bed (without wood I can just pick mine up and walk around with it on my back).

The resulting 2450-2550 pounds should be pretty close -- +/- 200 pounds isn't going to make any difference (it's the weight of a man sitting in the cab).
