2015 6.2 MPG towing results

[Fishbait]

I pulled my 19' boat which weighs 4000#'s with trailer,full tank and gear and averaged 12 mpg on a fairly flat Texas highway. This was an 80 mile one way trip averaging 65-70 mph in tow haul mode. The return trip was on back roads with hills and curves and I averaged 11.5 mpg (less weight as the tank and cooler were empty from my son and his friends).

 

I have the 2015 6.2 LTZ short bed with 3.23 gears without the Max Tow package and the truck pulled like a dream. On the highway the truck was never hunting for a gear even going uphill. Most of the time I could not even feel the boat and trailer behind me . Acceleration and passing were effortless and the transmission shifted flawlessly. My wife even commented on the fact that the truck rode so great and she couldn't tell we were hauling the boat. I had 2000 miles on the odometer at the time.

 

I pulled the same boat in my 2014 5.3 and I averaged 9 mpg on the same trip. The 5.3 was a long bed crew cab with the 3.73 gears. The truck pulled the boat great but does not compare to the 6.2. I put 24,000 miles on that truck with zero problems or issues.

 

All in all I am very pleased with the capabilities of the 6.2 and have never regretted trading in my 2014.

Thanks for the info. I watched TFL on YouTube pull 7K up the Eisenhower with a Denali 6.2/8 speed 3.23 and he had to stay off the throttle a lot of the time to keep from speeding. The 6.2 8-speed is probably the closest thing to a diesel now in the sense that it really does have enough jam to toy with it's weight ratings.

 

I wouldn't dream of not getting the 6.2 but buy the sounds of the 5.3 is a perfect all round choice, too. It's easy to find a 1500 Denali 5.3 in my parts but the 6.2's and 3500's are snapped up quickly.

Im with ya man! I towed for the first time this weekend as well with my 6.2. Pulled my 21' Centurion up to my lake house for the summer and it pulled like a dream. My old 5.3 would struggle hard but not my new truck. Once up to speed, it stayed even going up hills without downshifting, which tells me theres plenty of torque there when you need it. The only thing i didnt like was the lack of an HD suspension bc the boat is fairly heavy and it was a tad bouncy but thats to be expected.

 

MPG's were around 12-15 id say.

Towed my 8000 pound toy hauler for the first time this weekend my 2014 6.2 with 3.42 pulled it without even breaking a sweat, I towed it for about 200 miles and got 12.5 mpg....the 6.2 is a strong motor for sure.

I just remembered I was running E85 in the 2014.That was the reason my mpg was so low.
