I've got 355 miles on the clock on this tank of fuel so far. I've driven from Roseau MN (10 miles from Canadian Border) to the Mall of America Bloomington, MN

Pretty damn good. 3 persons and some light luggage. Been driving 56-60MPH only surpassing that to 63MPH to hit Aero then backing off.

Mind you MN and the lakes area I have traveled through is very hilly terrain as well.

Like it. Have to say here lately I'm in an mpg mode as well. Paying a lot more attention to acceleration, speed, gear, & idle time more than I normally would. Pulled 30.5mpg (EVIC) on a short 60 mile cruise this afternoon. That was ideal situation, other then the 32F outside temp. Overall on this tank I hope to get ballpark 24mpg, up from the 20/21 I've been getting all winter long.

These trucks are very fickle beasts when it comes to efficiency.
 
Yes they are when in cruise control it's amazing how a 1 mph increase can result in a 2 to 3 mpg loss...my gearing seems to like 59mph and ~72 mph the best.
 
What is aero? Aerodynamics I dont have that on my 15 Laramie.
 
It is a feature on trucks equipped with air suspension
 
Ok..makes sense
 
At 63+ with available air suspension or the limited model the truck lowers about 1 inch to help break the wind as long as you do not have a 7 pin trailer connected or are in tow/haul mode then it bypasses it.

Or if you have over 2500# or so payload it overloads and will only maintain standard height. The factory air can handle 10k# before that happens. My trucks gross is about 6800#
 
So I had a lot more errands in the cities and short commutes though it was warm and I did not have to idle near as much as at home which is about 30 degrees cooler and then got hit with rush hour leaving Minneapolis a headwind on the way home but I still made it to bemidji before my evic was showing a range around 115 miles and I needed about 150 to make it home comfortably. I can't show exact evic numbers because I've never reset my trips or MPGs since I took the Truck off the lot. Trip A includes assembly hours miles and PDI's and trip B and the MPG is lifetime everything I have ever driven. 23k
 
Here's hand calculated total anyways when I did stop and fill. Though I squeezed 24 gallons in the evic said I had range of almost 4 gallons remaining. I was at a little shy of a quarter anyways.

I really won't complain about giving up an hour round trip having slowed down
 
I'm averaging 25.8mpg over the first 1700 miles. Pretty good I think. Watching that mpg meter really helps you to figure out where it likes it the best.
 
Anyone in a warmer climate that doesn't need to idle should be averaging around there with sensible driving. Idle free climate just isn't my case

Welcome to the site! Nice MPG numbers as well. :)
 
It's been a while since I've posted. Hi @BoostN ... I have about 18k miles on the truck, we use it for a delivery vehicle so we do a fair amount of freeway driving 150+ miles round trip 2+ times a week at 70 mph. It gets 28-30.5 mpg regularly which is AWESOME! Our old (gas) truck was getting around 14-16mpg. I have done some round trips, around 300 miles at 60 mph (cruise control) and hit 34 mpg.
I love this truck, my kids love this truck and my employees (yes, they drive it too) love this truck!
 
I have had peaked 37 mpg (imperial), 31 mpg (US). My life mileage (total gas used in 22,000 KM is 26 mpg (Imperial) and 21 mpg (US). Keep in mind, about 7,000 was towing and most of it was city driving. Only did several highway trips.
 
I have about 15000 miles on mine right now and for the total amount of miles I got 26.6mpg so far. I run a 795 mile trip two to three times a mouth at 73-75 mph with the cruse on. My best for a tank is 29.5mpg. So far I'm really happy with this truck, best I have owned so far.
