New guy here...   Hoping to give my .02 in case someone is considering the 3.0. And it’s also for the guy who is believing all the negative BS reviews like I almost did.    Long post, so

When I was shopping in November, I had salesman tell me: -1500 diesel didn’t exist -it’s a duramax/Allison so it will last forever -It’s a 1500 but can pull like a 2500 with the diesel

Crew cab short box?

Ft Wayne, Indiana assembly builds some crew short box. I am pretty sure all the CarbonPro trucks are built at Ft Wayne because the carbon bed supplier is very close by. I don't think the engine choice has much to do with where the truck is built though.

Do you have the "diesel off road package"?  I wonder why your payload is 200lbs lower than mine.

The regular 6.5 box trucks has a lower payload rating compared to the short 5.3 box trucks, the off-road package may also add a few pounds over the Z71 but I seriously doubt it.

So we got our 2020 3.0 Crew cab/short box denali in December and only had the chance to put a couple thousand miles on it.  ‘This week we finally got to take it on our first big trip out west.  We are half way through the trip and going through SD and WY we avg’d about 75-80 mph. We have 4 people in the truck and bed has luggage and supplies and we are getting about 25mpg. I realize if we went 55mph that we’d probably get closer to epa numbers but I’m pretty happy with this result. Additionally before this trip, with around town driving, we were getting consistently getting 24-25. We took this same trip a few years back with our suburban and averaged about 18-19 mpg.

Overall truck is doing very well and no issues- Its a pleasure to drive and comfortable for all.

Anyone towing in the 7000-9000 lbs range care to comment?  Debating between this and a Diesel HD - tow about twice a month, with a few weeks of straight towing here and there.

Yes, i'm towing a 7x16 enclosed. 7000 lbs is very comfortable for this truck. Only on steeper grades will it drop from 10th to 9th with cruise set at 65-70. Good news is the tow/haul mode is very well tuned so it will hold 9th for duration of the hill and prevent gear hunting like the gassers tend to do. Furthermore, 10th and 9th are such a close gear ratio that you won't even notice it if you are looking for it. I can't speak for 9000+ towing but unless you regularly tow in very hilly terrain, there's ample low end torque, smooth, smart and quite transmission works with it flawlessly. 

PS - anyone not sold on 3.0 vs 5.3 gas, wait until you go down a steep hill in tow/haul mode and listen to the turbo spool as it's vanes close to create back pressure. Truck will automatically down shift and turbo works to slow the truck down saving your breaks. Might not mean much to you but it does to me:)

Very interesting thread after 28 pages. I've been lurking as I'm considering a new pick up come later this fall and leaning towards a 2021 Silverado 1500, and now considering the 3.0 Duramax engine. It would be my first diesel so I am as ignorant as they come in regards to diesel engines. For those who have experience, do you see an issue with me only driving it 5,000-6,000 per year....it's going to sit a lot and mostly get used on the weekends for hunting, fishing. camping and long highway trips to see family. Thoughts?

Anti Ignorant Rule #1.  Put diesel in it.  (Dont laugh, when you're trained to head to the pump, diesel isnt on you mind)

 

Mine is used for weekend hauls and very short trips occasionally during the week (otherwise I use my car).  So far, totally content. tow a boat 9000lbs and and enclosed trailer around 2500lbs.  

 

1500 miles and I still have not noticed a regen - although Im sure its happened. I guess that is a good thing.

      Multigate Connector Difficult to Connect Fully

      By Another JR · Posted

      Hi All, I operate my 2021 3500 SLT most of the time with the tailgate off and in a crate because I have a slide-in camper. However, at least once a year, I take the camper off and put the tailgate back on. Recently I installed the tailgate, but had a hard time getting the connector bail to swing to the fully latched position. The connector seems to fully seat, and everything works, but the bail doesn’t swing to fully latched position.  It swings almost there but stops and I am afraid to push it any harder.    Does anyone have any advice on cleaning or lubrication or anything else I should be doing?  i know how to properly operate the connector. During the time the tailgate and connector are off, i have a double plastic bag over the truck connector secured with rubber bands to keep it clean, but it still had some dust in it this time when I blew it out with compressed air. I didn’t want to spray it with anything other than air without doing some research. Thanks.

      There are a lot of spammer's that do that, quote something and add some commentary to make it seem legit, but modify the quoted text a bunch making sure when posted it's long enough to be "click to expand", and either immediately insert a spam link, or come back after some time and edit it to add the spam link.

      Hello @jaszr2 Do you have a link for the item? I put a replacement bumper on my truck and consequently had to relocate the shutters. I studied on them a while, and figured if you left a couple key blades, you could get most of the airflow with probably no throwing codes.

      In the 6.6 gas thread, I added information in my fluid change thread about these gauges and temperatures. With very limited data, it so far looks like ~30 degrees difference between front and rear.

      Fluid Change Questions

      I know; crap pictures.   Anyway, as a finale of sorts to this thread, I had replaced both differential covers and since they had the capability of adding temperature probes, I did that. These are MaxTow analog/digital gauges with stepper motors. They'll flutter around like crazy for a moment and start at a nominal 100 degrees Fahrenheit.   I drove a 30-mile loop to the grocery store, averaging 70 MPH (as much as 80 to see if there was a quick spike in temperature. The air temperature is 102 (ambient ?). but the first pic is 7 miles into the trip. The second is getting back into the truck after leaving the store; differential temperatures dropped about three to four degrees in 15 minutes. The third pic in on the road to my house, about a mile away.   In that run, I saw a high of 150F on the rear differential, and 121F on the front. I'm sure a longer drive or towing will see higher than that, and when that happens, I can update the observations.
