i'd personally have to jump on the dually just cuz you know it wasn't whored out, prolly didnt have too many heavy loads on her if any at all, and ya know most old men keep up w/ the maintenance @ the dealership. Lets see the pics of the dually to make this fair...

Tough choices man. I like the originally posted 350. But i say get something closer to stock, so you can make it your own.
That new bedliner in the 2007 would make me question what was there to make them want to cover it up.
