This is my 1st one ton, and my 1st dually, so I was really excited to get some miles on it. To start, this is not my first Cummins, I have owned:
2005 5.9
2007 5.9
2011 6.7
2013 6.7
2016 6.7
My 5.9's were by far the easiest trucks. The 2005 would eat transmission unfortunately. The 2007 was my easiest and most durable truck to date, that's why I drove it the longest. My 2011 was interesting, constant regens, and fuel diluted oil. 2013 was a big improvement, quiet, great ride quality, good power, my most fuel efficient one to that date. My 2016 was lousy, hands down, the worst riding truck I ever owned, and the programmed in throttle delay was deadly in my opinion! Ditched that thing quickly.

Now I am back in a Cummins for 2021 (coming from two 6.4 2500's) in between. The drivability in the new 6.7 is outstanding, and this truck is huge! That deadly throttle delay is no longer present, it accelerates like a normal vehicle now. Ride quality and comfort are outstanding for a 1 ton dually, and light years better than my 2016 2500. It drives normal, accelerates hard, its quiet, comfortable and very easy to drive around town. In this chassis, I no longer feel the extreme mass of the 6.7 out front, my 2500's always felt like I had 3 yards of wet concrete slung out over the front axle.

I have not towed yet (was working on getting 500 miles on it first) but will be hitching up next week to the camper. I really look forward to comparing it to my 2019 2500 6.4 8-speed 4.10 gears that I have been towing with. Also interested to see what the fuel economy difference will be. Overall, I am extremely pleased with the 2021 so far, and hopefully, I will get many towing miles under it here soon.

Glad to hear all is well.
I test drove a Cummins before I got my 19 6.4- it was a 15 or 16 2500 and there felt like a solid one second lag between pressing the accelerator and the truck doing anything- this was at a highway onramp. No thanks. I'm glad that's been rectified, enjoy that big red beast!

Cummins High Output 6.7L
Hey there, Firebird. Congrats on that beautiful red '21 Cummins 3500 dually !! Being a dually, that must be the high output version of the Cummins 6.7, with that huge, heavy duty Aisin automatic transmission. I have the same drivetrain in my '19 3500 dually, now with about 8,700 miles on it. What trim level did you get? Mine is a Laramie, crew cab.

Glad to hear it drives as good as it looks. I have just about 650 miles on my big red 2500 long box and am very happy with it so far too. I don't pull much so the 6.4 is working out as a great choice for my new hunting rig.

I loved my 6.4's, and after owning the 2016 Cummins, they were so much better to drive than it was.

Mine is just a Tradesman, I've never owned this trim level before, but it was all that was available. Can't wait to tow with it next week!

Pretty truck! Looks just like mine, except I have SRW.
Not sure if you are aware, the owners manual says to not go over 50mph for the first 500 miles of towing.

Cool, thanks. I'll be on back roads this trip, so will be way below interstate speeds
