Is anyone out there towing 6000lbs with this new engine and the max towing package? I'd be interested in any feedback that's available.

we have the same engine in a gmc AT4 i pulled a 15,000 pound boat to see how it would handle it the thing comes alive like a tractor puller i was pulling up a hill from a dead stop and was doing 60 at the top still shifting the 10 speed is awesome so is the engine

Thanks for your comments boostbros. Giving this a bump in hopes of getting more feedback.

Not sure if this will effect your decision or not:

this engine is very well engineered and its a inline 6 cylinder even with the offroad tires that come on the AT4 we are hitting 31 to 32 mpg guys with highway tires are around 34

Read the review in Car & Driver. They loved it.

I heard you had to pull the engine at 100k to check a belt in the rear of the engine.

External oil pump belt. I think the replacement interval is 150K.

1st year blues hit many manufacturers. I personally prefer to wait for min of 3rd year of something brand new to the market.

I have this in an AT4 Sierra 1500/Standard bed. I pulled my 34 MTI with it no problem. I also hauled a 16' trailer with two big Harleys. Only noticeable issue sis that it drinks DEF like fuel with a load. About 350-400 miles and it needs DEF.

When i got it I was getting high 20's in mileage and after adding wheels and a level kit I get about 21/22. But I run it 80+ everywhere. 20k miles wo a hiccup
