What is your goal? Driver, street pounder? Cheap build? All out build? Condition of your truck? Etc, Etc.

The max mileage is a trick question depending on how it was treated. I've rebuilt some trucks that were babied and had 225 or so and they ran almost good as new. If you get one [an older one] a 03 or 04 with bigger miles change out the intake manifold as they tend to have a vacuum leak after they age.
