That is on a much lighter, less capable pickup than the 2500. One of the many reasons I got a 2015 2500 instead of a 1500. The 6.2L power numbers may be a little better, but no 1500 with a 6.2L is rated to 20,500 lb total GCVW like my 2500.

According to the 2015 Trailering Guide the 2500 HD is only rated at about 1,300 more lbs than the 6.2 Max Tow. 13,000 vs 11,700 assuming both trucks are 4x4 crew cabs

If you're regularly pulling 10k you probably should have gotten a Duramax anyway.

Premium is not required. I have never put 93 octane in mine. I trounce your fuel economy claims and can out pull your 6.0. What a stupid argument

You better read your owners manual

But I can assure you that I would not pick the 3/4-1 ton gas engine from GM...it is far outclassed by other competitors and is in deep need of an update. It's inefficient and it tows like an absolute dog.

TFL gave it the golden hitch award for gas HD's!

Went for a nice ride on the highway today:

2015 Max Tow GMC Crew Cab, 33" BFG AT KO2, 2.5" lift, no front air dam, Diablotune with AFM disabled

Not bad!

My best average went up to 22.6 mpg over the weekend. Wasn't paying attention to my mileage since I didn't really go anywhere or on the highway at all. Did go to a friends a couple miles out in the country but that's it.

going to put the air dam back on (at least with about 4 bolts) next time I go for a long drive and see if that makes a noticeable difference.

I did the calculations in another thread for the 6.0 vs the 6.2 and included some scenarios with gas prices going up/down and mileage

I did some numbers.

Assuming current gas prices (2.70 for regular and 3.10 for premium) at the station down the street and 14 mpg for the 6.0 and 17 mpg for the 6.2, you're looking at only a $5 difference for every 500 miles you drive. That's a penny a mile. If you drive 15,000 miles a year that's only $150.

If gas goes up 70 cents to 3.40 for regular and 3.80 for premium, the advantage of the 6.2 doubles to almost $10 every 500 miles. Still only $300 a year if you drive 15,000 miles a year.

However, if gas goes down like they are saying on the news, to $2.00 for regular and $2.40 for premium, it's pretty much the same cost to drive either vehicle. You're talking 16 cents difference for every 500 miles driven, $4.80/year

Now lets say you/re get only 12 mpg in the 6.0 and only 15 mpg in the 16.2, 2mpg less for each truck than the first set of numbers. Lots of city driving or something. With gas at today's prices, you're back at $9 cheaper for the 6.2 every 500 miles.

On the other hand, lets say both trucks get great gas mileage. 17.4 for the 6.0 like Copperhead posted, and 20.6 for the 6.2 like the other guy posted. The 6.2 only enjoys a $2.34 advantage over a 500 mile trip. That's $69 a year.

People can debate the MPG of both trucks all day long, and it plays a big part.

You guys with the V6's and the 6.0's can find another thread to stink up. This one is for 6.2 gas mileage only :roll:
