If it makes you feel any better a 2 MPG gain over 7 MPG is a 28.5% improvement. OTOH, do not do the math to figure out how many towing miles until you've made up the cost premium.

Best regards,

25-30% is what I figured diesel gets over gas so it appears he has a good increase to me, but on the other hand he drives with a heavy foot at 75mph.

No need to figure out the math to figure out making up the cost difference. That's like figuring out the math for buying a top trim package, I bought mine more for less stressful towing and not for making up $$ at the pump. Some people like leather, air conditioned seats, and 15 cameras, I don't really care about those things but I like a comfortable towing experience. How to you put a price creature comforts? I paid a lot less for my truck than a top trim package in a gasser. Their isn't a right or wrong way it's just what you prefer while staying within your budget.

Others have stated they get 12+ mpg towing large fifth wheels is what I was expecting. This is my first diesel so I only went by what others posted. Obvisouly they are full of ****. I just got back from a 800 mile round trip with the 5er and only managed to average 8.6mpg @75 mph in Pa and NY.


Have you tried 80mph?

Are there 75mph highways in New York?

I guarantee if you slowed to 60 you would be over 10mpg.

I find it easy to tow slower than everyone flying around at 75-80 on the highways. I just set the cruise at 55-60 and let everyone pass.

No need to worry about constantly slowing down for slow cars (since I'm the slow one), then speeding up again. Or planning passes with the trailer in tow.

I just cruise until we get there or need to take a break. With a 42G tank, even at gasser mileage I'm ready for a break before we get to low on gas.
