Posted By: Sako76 2024 GMC 1500 AT4 3.0 diesel - 03/10/24
Was thinking of getting one, anybody own one? I would like to hear about your experiences, especially fuel mileage and comfort! Thanks.
Look at the 3.0 diesel thread
Looking for comments on the AT4.
AT4 has Better ground clearance, Front and rear lockers,4 hi and lo, better off-road tires, reduced payload, and towing capacity.

I looked at the AT4 comparing it to the Sierra Elevation Max tow package I bought. If you want to go off-road the ATF is a better option, the 3.0 diesel is the only engine I wanted.

I just did a 250-mile drive, in my 1500 GMC Sierra Elevation. saw a max MPG of 29.1 27.6 average, great power. Love the 3.0!
Thanks kk!
I had a Trail Boss with the 3.0 Duramax. Chevy version of the AT4. Great motor. I have owned 3 of them and put about 100,000 miles on total on the 3.0
I think a Trail Boss is the Chevy version of the Elevation. (see correction below)

The ZR2 is the Chevy which is comparable to the AT4. I have a 6.2 in mine, its been to Montana and Texas and is the most comfortable pickup we've ever had. Frankly, comfort wise, its not even close and we had LTZ's before. I freaklng love the seats, the interior, the suspension, everything. When its time for new tires, I expect it to get even more comfortable. Not a huge fan of the Wranglers it came with but they've been better than I expected they would be. And its an absolute animal on the ground, we took it places a truck shouldn't go.

I would probably get the 3.0 if I had it to do over again, owing to my usage patterns which include a fair amount of miles. But its not a for certain, the diesels aren't as user friendly IMHO.
ZR2 = AT4x
Interesting, I stand corrected.
