I looked long and hard for an un-modded truck. But, I wouldn't be against a 7.3 Ford with the following mods: 4" exhaust, pyro/boost/trans temp gauges, and a quality chip, not a plug-in-the-OBD port tuner thing. A rebuilt auto trans (with shift kit or programming) or a 6 speed. But, you'd only want to buy this truck from a sane-headed individual who did things for the right reason, rather than to roll coal and race his Chevy-owning neighbor.
The real reason for a nicely modded truck is that the last guy will have spent $2-3K getting it there, but it would only add $500 to the sale price of the truck, if that.
