I really like my 3.0.  Its task over the past 1.5yrs was to be my daily, pull my boat and my 6800# travel trailer.  Did remarkably well.  I didn't like the 9300# towing limitation and next thing you know the 2022 3.0 Dmax can tow 13.3k, not that I think it's a good idea but that truck is underrated.  I would not hesitate to recommend the 3.0 for what I used it for.  I did add a S&B filter, Load lifter 5000, aftermarket wheels and level kit.

 

Upgraded my travel trailer and it weighs 8200# empty.  Eventually a 5th wheel is coming, prob in 1.5 - 2yrs.

 

I'm going to do the same to this, add bags, aftermarket wheels, level kit and CAI.

 

Tuesday she'll be here!

I did the EXACT same thing in May of this year. I had ordered a Sierra AT4 1/2 ton 4x4 with the 3.0 in December 2020. While we were waiting we decided to order a 27’ Airstream that weighed in at 6800 lbs max. As luck would have it, the truck came in two weeks before the trailer was delivered. 
 I really enjoyed the 3.0 power and economy on the highway. Sooo smooth!  According to published data of payload and towing capabilities, I felt the AT4 would be close to capacity but “should be OK”. I picked up the trailer installed a  Blue Ox Sway Pro and headed 70 miles home. 
 Although the AT4 had more than enough torque and horsepower to pull the trailer, it was evident I was at max payload. A stop at a Cat Scale confirmed my seat of the pants feeling. I was over my 1430 lb payload by 290 lbs and close to max rear axle load. I was at about 75% road ready loaded.

 When I got home, I knew I could not travel 10-12k miles a year towing with the AT4. Very disappointed, it was evident I had to trade up to a 3/4 ton P/U. To my surprise the AT4 increased in value due to the chip shortages that were delaying new truck deliveries. 
 In a stroke of luck 4 weeks earlier a customer had cancelled his order for a 2021 Denali 2500 because he did not want to wait another month for delivery. I jumped on the opportunity and I had the truck in 8 days. The price difference after the trade was $9.5k! 
 I’m at 16k miles with the Denali. It has a 3055 lb Payload and that monster 6.6 Duramax! I’m extremely lucky and happy I decided to upsize. The trailering difference is like night & day.

Nice looking truck.  Yea 3.0 Dmax is definitely a good truck.  I was getting 23 mpg with 3.73 gears going 70-75 not towing.  With 3.42's it would have been much better but I wasn't complaining at 23.

 

Supposedly the 6.6 Dmax gets good mpg not towing also.  Looking forward to getting mine!

6.6's can give good mileage, but not like the 3.0.

 

Similar tasks, my 3.0L is running a little over 25 lifetime (1 year, 16,000 miles) vs the 6.6's which generally gave numbers high teens. 

Of course they all will show higher 'cruising down the highway' numbers.  Above numbers tank averages.

 

 

You'll love they way the 6.6 pulls!

Congrats.

This guy.  You have a 3.0 and the 6.6?  Nice.  I'll be happy with 20mpg tbh.

Sorry if I mislead.

I've had 4 of 6.6's (one at a time) -- 2004 LLY, 2010 LMM, 2011LML, 2018 L5P 

I have the 3.0 because my needs no longer require a 6.6.

 

When the heavier jobs were done I tried 1500 8 speeds.

A 6.2 (NHT was unavailable when I was having it built) and then a 5.3NHT.  

 

After years of running 6.6's I just couldn't get happy with the way the gassers drove.  Pulling an enclosed utility trailer across the country with the NHT was the last straw and went to an '18 6.6. (even though the jobs for it didn't justify that much truck)

 

3.0 / 10 speed seemed to be what I'd been 'looking' for. 

I did order the 'standard bed' (so with the new body style, it's a little longer than the 2500 crew w/standard was.

 

Imho, they've made the 2500's too high/tall for ease of use -- getting in/out and access to the box.

A lifted 1500 (AT4 or either Trailboss) are still shorter than the 2500's.

You didn't mislead.  I was just making a joke.  I got lucky that a local dealer just happened to be getting a shipment of a few in.  So I put my deposit down and did all of the credit app stuff.  Tomorrow I'll pick it up.

    • Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-
    • Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.     
    • I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.
    • I do too. I’ll never be stuck again 😂
    • It has happened to me a few times. I carry a jumpstart-tire inflator with me.
