Triton V-10

I have a 2009 weighing in at about 21,000 fully loaded plus a tow at 4400. Mileage at 60-52mph runs generally in the low 6's. That is over 35,000 miles. I log EVERY tank in a spreadsheet so this mileage is 'real' not a meter or the occasional check. I did add the 5-star tune and I suggest that to anyone. Engine is noisy when pulling a steep grade and definitely above 65mph. No power issues even on very steep hills across WV.
