I have put several hundred thousand miles on 6.0 Chevys not towing for work. I have personally owned a 2004 and 2012. 2011 and up is a great towing platform and the 6.0 in general is a very reliable and low maintenance engine. When towing my 10k trailer my 2012 did run at very high rpms (4-5K) up hills and overall towing gas mileage was about 8 mpg. I traded because I found listening to the engine scream at 4500 rpm unnerving. Nothing bad never actually happened and probably never would have, but at those rpms I had visions of pistons flying through the hood. Overall I would say the 2011+ 6.0 is a good solid choice for occasional or sub-10K towing.

I have a 2005 Silverado now at 125,000 miles, 4:10 rear ratio. Been pulling a 32' Big Country at about 11,000 pounds with no problems at all. Fuel mileage is not so great but no worse than most gas or diesel TV's. Still runs as good as the day I bought it.

I had a 2011 Silverado 2500HD 2WD crew cab short bed. Was pulling a 8000lb TT. It pulled it with no problems. Fuel mileage was 9 on the interstate at 60. One thing I could not stand was the HOWL from the intake when it was revving 4K+ going on overpasses. It was constantly hunting gears even in tow/haul and locked out of sixth gear. I haul a 3K trailer every day in my work, and around town it was perfect, even getting 11MPG doing it. I will say that other than those quirks it was a great truck. My .02

We purchased a 2002 Chevy 2500 HD with the 6.0 gas, 4.10 gears with 78,000 miles. It is a big improvement over our 1500 Suburban. It's rated to pull 10,300 lbs so our 7800 trailer is nothing for it. It's best friend is a gas station, so starting looking for one at around at the 265 mile range!! Good luck. We love ours. Very comfortable ride and interior!

the chevy 2500 6.0 i think all come with 4.10 rear ends . as far as running at 4200 to 4500 rpm pulling passes . no problem the 6.0 can run all day like that . 4500 rpm is not that much for a gasser and never feels like it can't handle it or anything even close those that do get that feeling don't know much about trucks or gas engines . i pull my xlr29hsf toy hauler weighs in fully loaded at just over 9000 lba with a tw of 1200 the 2500 hardly knows it's back there . i use the andersen wdh and never any issues with sway or bounce the unit tracks as one with the truck . mpg not towing is a low of 13 and a high of 15 depending on how you push the peddle . towing is 8.5 low and normal 9 to 9.5 . i only have the 4 speed and wish it was the 6 but it does the job from Colorado to Fl and Fl to Colorado to montana and back again . never misses a beat at 138,000 mile i will look to up grade in a couple yrs . the 6.0 is a 300,000 mile engine . just change the oil

2016 6.0 6 spd in a 4500 Express motorhome dragging 15k total (rig and toad).
Pulls adequate. Not breaking the sound barrier by any means. I drive 60-65 most of the time. 50-55 up the steeper hills.
For the price difference to a diesel and the 10 mpg I am averaging, I am more than happy with it. Simple maintenance also.

The 6 spd makes a huge difference over the old 4 spd.
Very happy with my choice...for now.
Feels rock solid.

We have the 2011 2500hd with the 6.0L motor. Has about 70,000 miles on the clock now. We tow roughly a 9000 pound fifth wheel. We've toad all over the Midwest and the Ozark Mountains. She is thirsty and he will not win any races. But the 6.0L Chevy does a great job towing our 5er.

I own a 2011 Silverado2500HD 6.0 gas with 4.10 rear end. I haul a 34 foot Crusader 315RST. Our last trip was to My. Airy, North Carolina for the FROG Rally. I've made no modifications to the truck and it performs extremely well. Last year I took our rig to Lake Lanier in Georgia by way of Elkhart, Indiana, Louisville, Kentucky, and Nashville, Tennessee. Again no problems on that trip. Something to keep in mind is I DO NOT drive over 60 mph while towing. I have not found any inclines that have forced me to reduse that speed. My mileage varies between 9 and 11 mpg, again depending on terrain. Hope this helps.

2012 4x4 Standard Cab, Long Box, 6.0 gas, 4:10 gears. I had a 2008 with 3.73's and @ 62mph the slightest incline it hunted for the right gear pulling a Wildcat 26FBS 6640 lbs dry. Bought the 2012 because of the 4:10 gears and pulled like a dream. I usually pull @ 62mph and the gas mileage went up 1 - 1 1/2 mpg. Pulls the new 5th wheel like a dream (8162 lbs dry) 8.6 -9.2 mpg.
