Chevy all the way I have an 07 and just flat love that truck 40k on it now and not a single problem.Much quieter and better driving then Ford or Dodge. With the cruise on @ 70 it'll give you 21-22 mpg no problem. If he happens to buy a 2 car trailer and a couple of 911's while he's here it'll handle that fine too
