I'm about 3 hour north in Knoxville, and have noticed about the same ratio. I was at the dealer getting a key programmed and only saw 1 2013 6.2L. I love mine, but now that I upgraded to an 8200lb TT, wouldn't mind getting a newer Diesel as well. I just don't want to pay for it, and the 6.2 with 4.30 should be more than enough for my needs. Plus, I wouldn't want to get rid of ANY of the options that I've grown to love in my Lariat!
