As a l8t owner, I don't think I'd ditch my 7.3 Zilla to get one. Nothing against the 6.6,but the Zilla's issues are pretty few and far between. Yeah, early ones had cam/lifter delam issues, but from what I read, that's all been sorted.
Buying new, I'd say flip a coin, as both are solid, but doubt I'd trade my Zilla for a l8t over delamination fears.
Honestly, I don't think you can go wrong with any current HD gasser, even Ram. They have hands down the best trans, and the 6.4 Hemi doesn't have nearly as many "tic" issues as the 5.7s.
Good time to have a gas HD.
Fwiw, my 25' 6.6 with 8,000mi uses basically no oil.
The dealership told me they have no idea. They also stated that the compressor has had six different part numbers too. Seems they may have issues making one that works. The loaner truck I had worked just as bad. The first 1-2 min was pure hot air before it even attempted to start cooling. After that, it didnt react that way the rest of the day.
Happy 250th, 4th of July-
We have a 2024 gmc 2500hd sle doublecab 6.6l gas 4x4, 3540 payload, towing a 2015 Rockwood 8329 TT, 35' with tractor supply box on back.
Dry weight is 7200, but the important number you need to always use is the 9000 GVWR.
It tows it just fine, that 6.6l gas engine is a work horse, Later-
FYI - it's not your signature. It's in your profile. Go to your profile and edit it. If you don't want to do it, fine. Don't be criticizing others because they say you drive a vehicle that you say you sold. It's on you.
And if you don't much give a ****, then why are you always responding and complaining about others?
