2012's
 

Has anyone bought a 12 yet? I see that there are a few on ebay already. I'm really wondering if the 800ft lbs is just sucking the fuel quicker or is adding to the mileage.I would appreciate any inside information before I go another $50k in debt.

I have an 2011 with the 800 ft-lbs with 4800+ miles. I get 14-15 running 70-75 mph, but only 7-8 pulling my fifth wheel at 14500 lbs. A long time before its broke in.
