2014 Chevy Silverado long bed, crew cab, 3500 dually diesel with Duramax: 90,000 miles now. About 70,000 of that was towing a trailer. Still going nice and strong after 9 years. However, the window buttons are in their third round of failure. We've had them replaced twice now and, again, there are 2 doors (passenger side for both, front and back) where the buttons have quit working at the drivers door.
Round 3 replacing them, coming soon!

2007 2500HD LBZ.
171,106 miles and still going strong. I bought it at 125K miles and 50-60 percent of my use has been towing. I have upgraded shocks, springs, wheels to what came OEM on the 3500. According to the label on the axle, it is also what came OEM stock on the 3500.
I have replaced the ball joints and tie rods/ends and brakes and shocks, batteries etc. that are just normal wear/maintenance items, but nothing real major. The engine (see further down), transmission and transfer case are all good. It has thrown a code twice in the last six months or so that my mechanic says tells him that the vanes in the turbo are beginning to wear/stick. He suggests I start saving for a new turbo.
Still, I expect to get another 100k or more out of this truck and honestly believe it will be the last one I ever own. Another 100k miles, for me, at my usage, will put me at age 86-87-88 and I doubt I will still be pulling at that age. This truck is a beast and I love it.

Hey peanut , I too have 175,000 miles on my cummins 6.7 and she still purrs like a kitten i fully expect expect to see 500,000 if the rest of the truck holds up. Turbos can get a little sticky. Try "hotshots" products i.e. fuel treatment every 4 or 5 tank fulls and a half bottle of anti stiction that goes in every 6 months.I am sure you will notice a big change!

Well not a DMax, but out 2001 Ram 2500 with Cummins 5.9 was towing strong at 315,000 miles. We were towing out about 13,000# 5th wheel, with a 5 speed manual, and 3.55 gears.
Current TV is 2016 Ram 3500 CC, LB, Aisin, 3.73's, bought at 27,000 miles and currently at 92,000 miles.
I think any of the big three diesels will go well over 350,000 miles even with the emissions equipment.

306,000 on a 2003 Ford Excursion 6 0 diesel! Tows our 9500 pound camper like a BEAST!
Not studded, original injectors, deltas are no higher than 13 degrees when towing.

Only 54k so far
I have 54k on my 2019 3500HD. I use Optilube or hotshot secret in every tank. I also have an aux fuel tank with a good filter. I only put fuel in the aux tank and transfer into the main tank. That way I know the quality of the filter. That should keep the GM filter in good shape. A duramax can go an easy 500k with regular maintenance. I use all Amsoil synthetics.
Fuel economy is way better than what I see on frinds dodges and ford's. When you tow a large 5th wheel youn can't cut corners on servicing. 40k mi of my low 54k mi is towing. I know that is low milage but that is when you work to keep one new not after 500k

Miles on my Duramax
On my 2009 Dually I’ve got 175k towing my 5th wheel. No issues other than replacing tires and brakes along with oil and fuel filters. Best part is I don’t have to deal with DEF!

Had an '05 GMC Dmax with 176k+ miles, only issues were a critter chewed wires twice. Would still have it but got side swipped by a truck & they never could/did get the passenger side front door where it sealed properly, wind noise drove us nuts.
Had 138k+ on a '13 GMC DMax that had the turbo replaced at 100k & DEF tank & pump replaced, all were replaced under warranty.

2011 Denali 2500HD
299,870 miles today! I bought this truck new, and didn’t start pulling a my Keystone Laredo 296RL bumper-pull until 2013. Maintenance has been an ongoing thing. 90% emissions, def, DPF, et al issues. Most annoying is the dreaded limp-mode. Usually, I get a warning on the DIC, but the last one hit as a surprise. It’s all stock and all working (at this time). Rear fenders rusted from the inside about 100,000m ago. Front and rear painted bumpers radiating about the same time. Replaces bumpers treated the fenders and put flairs on. Actually looks pretty good. Garaged nightly when home. Pulls the trailer with ease. 18-19 mpg average, with 12-14 mpg pulling, depending on headwinds. Yes, I’d buy another…

2008 GMC Sierra with 123K, about half towing 13K 5th wheel. Replaced three glow plugs, brake pressure sensor (on side of Master Cylinder was getting "Check Trailer Brake System message), AC condenser to date. Recently got "Check Engine" light, scanner showed codes related to Turbo, dealer check advised replace Turbo. Have extended warranty so most of cost, about 3100, will be covered. Just reached 76 years so this should be last truck for me.
