11mpg most of the time. (no matter how I drive)  15 with the cruise set at 75.  So here's my question:

I have the tow package which supposedly has a different rear end in it than the stock.  I'm assuming that's a lower gear for towing and more power?  So what if i don't need all that towing power, can I put a higher rear end gear in it?  Would it make that much of a difference?

Back in the muscle car days my dad told my about how he had 3 sets of (rear end) gears for his 68 roadrunner.   I don’t remember the ratio’s (he had them memorized) but there was one set for everyday driving, one set for short racing and one set for highway trips and that it was about 1/2hr to switch them out.  Granted I’m not proposing having a different set of gears for different occasions like they used to but doesn’t it make since that if your NOT towing heavy loads to put a higher set of rear end gears in it?    It annoys me that my father-in-law’s extended Silverado gets the same highway mileage as my Titan does accept he’s PULLING A FIFTH WHEEL!!!  (He gets 21 normally)

Then of course the question is does anyone actually make gears that will fit in it?
