How are you liking this vehicle? I have same delivered end of October, now done 2400 miles since, As you notice in my signature, I changed all tires due to a need to drive the vehicle across the border to BC Canada, mpg has improved to 14.6 average from 13.3 which is good, not that I'm bothered but happy with the fact the engine is breaking-in. I initially had lots of driving comfort issues on less than perfect roads, perhaps due to its stiff suspension. Reducing tire pressures to 42-45 cold all around on better tires plus the fact I've now done over 2000 miles, I see the comfort factor improving. Be aware I'm not hauling or pulling anything with this truck, I bought it for its power, diesel and fun. Keep us posted on your experience with it.
