I think in the end one is going to take a hit somewhere, so while 20mpg's is at best marginal for its class, I think better reliability, less down time, and less depreciation can cancel out the additional expense on fuel cost. I have no issues spending an extra 10 bucks or so to drive 300 miles a week.
BUT... If the reliability is not there, the value proposition of the toyota is not as great as it once was.
I like the looks, I like the locker, i like the ability to run 35's, but without really good reliability, I am more drawn towards a GMC 2500 or Raptor.
