 This truck is great, I've shopped the competition and found this to be the best deal. I'm getting 18.9 mpg average in summer and 17.8 average in winter. I've upgraded to 89 octane this winter for a 1-2 mpg boost. you may get 16 mpg in the cold on 87 octane. I'm gonna try 93 and see if it is overall cheaper or not. I've got 6,000 miles on the truck and have had no problems at all. the 4wd works great, snow and hills are nothing. Great truck!
