99-06 vs 14-19 If you took the same truck (same cab style, 6.0,4x4, etc) is the 14-19 a superior daily and hauler? Would it be an upgrade from the early body style? My buddies neighbor has a ‘17 3/4 ton 4x4 work truck package that will be for sale soon and halfass curious if it would be a worthy upgrade from my 02 3/4 ton. If the truck in decent enough shape.

I went from an 02 2500Hd Duramax to a 15 2500HD 6.0. Both trucks being CCSB, the 02 a Silverado and the 15 a Sierra.
Daily driving, the 02 was a better ride. Front suspension was definitely softer. The 15 beats you up over every little bump. The rear end is about the same with the 15 being a little stiffer there too. While it is a rougher ride, the 15 handles better.
When hooked to a trailer, the 15 handles the weight way better. Doesn't matter if it's the 5th wheel (35' 12,000ish) or the bumper pull car trailer (I'd guess around typically 8500). It just feels more stable for the same load. The ride/handling is also better in the 15 when loaded vs the 02. Pulling the enclosed snowmobile trailer, both trucks are about the same.
Not going to lie, the Duramax pulled the weight better especially at highway speeds. The 6.0 does just fine. 0-50mph it accelerates with no problems. 50-70 it slows down a bit and you'll be looking for a bigger gap in traffic if you need to pass someone. It is by no means slow, but you know your pulling a load when it's back there. Probably doesn't help I know what I was missing/used to from the Duramax.
Build quality, I'd put them about the same. I think the GMT800 trucks are some of the best built/value in recent years. I haven't had any issues with my 15 in the 20k I've put on it. It's sitting at 102,xxx right now and according to the Carfax was a Canadian municipal vehicle before I bought it. The 02 had just over 300k on it when I traded it in. It had the typical issues for that truck (slow windows, hvac motors). The 02 was an LTZ with leather, 15 is an SLE with cloth. I do like the front seat in the 15 better with the center fold up arm rest/seat.
The 02 needed injectors, rockers/cab corners and a box. I couldn't justify putting that kind of money into it so it got traded in. I don't regret that decision one bit. The Duramax got better mileage doing the same commute. I think I averaged 15-18mpg with that truck. The 15 gets 12-13 at best empty. Winter fuel brings that down to 11. It does have 4.10 gears which I'm sure isn't helping. I'm not worried about the 6L90E. I flushed that when I got it and everything looked good when I had the pan off. As far as I know, the transmission is the biggest issue people have with the newer trucks. Mine only has VVT no AFM or DOD so cam/lifter issues shouldn't be a problem.
The only thing I don't like about the 15 is the wipers load up with ice real bad. It seems like I'm constantly having to knock them clean. Doesn't matter what fluid I use either.
While not the same truck. My work truck is an 05 2500HD regular cab/service box with a 6.0. That one scales out at 8800lbs on a regular day. Seat of the pants, that one feels like it has more power than the my 15. On paper it doesn't, it just feels like it. I'm sure it has to do with the more aggressive torque management the newer one has.

Just for reference, the 15-17 8 speed autotragic is a problem child. There's a class action lawsuit about them.
We've had so many arbitration and buy back about them, I have to set every one aside to do a long test drive. Even then 20% of them have been replaced under 100k miles.
You're not far from me, I'd hunt down the cleanest GMT800 I could find. They still exist.
My wife's '15 duramax is a very comfortable and nice riding truck. I fix electrical gremlins every other month.

The 8.1 is the entire reason I wont get rid of my 06 3500...

Personally I would keep the GMT-800. If you have a fairly clean example their values are starting appreciate. They have less electronics especially yours since it is a 99-04. Iirc 04.5 was the split when they added a BCM. 4L80’s aren’t the best but don’t seem to fail as often as the 6L80 or the 8speeds. We have 2500 express vans with the 6.0L at work. It seems every other week 1 of the 50 or so is down because of a transmission issue. Plus the 4L80 have been around long enough it can be rebuilt with better parts to live. The only somewhat major down side to keeping the older trucks are some of the OEM parts are starting to be discontinued. In my opinion the 06 and early 07 were some of last decent GM trucks built. 07.5-14 (recession era) trucks were garbage. Cheap and just shitty interiors in general coupled with whole LML CP4 fiasco. They are my least favorite modern era gm truck. 14+ got better with the LT and L5P engine families, a lot better interiors, up to date infotainment systems and ventilated seats. I’m fluffy and live in the south these make life better. Down side all the bells and whistles are tied to a module that’s expensive to replace and many require a relearn, pair, calibration, or ect. I got really close to buying a new 2500 in 2018 but decided to keep my 07. In 2020 I bought a 2013 that had a catastrophic fuel system failure. I fixed it and flipped it. A lot of people thought I was crazy for selling it and keeping my 07. To me there wasn’t enough of an improvement to justify keeping it. My 07 had about 15k less miles and you see way less clean GMT-800’s now.
My 07 now.

When gas hike went up, lot of 8.1 went for sale under 10k for while until diesel price went up and so did the 8.1 lol

I’ve never driven a truck with an 8.1 what are they like?
My dad had an 01 2500 4x4 with a 6.0 when it was new. I remember it doing ok but it seemed like much of a hill would make it would down shift and turn 4K rpm’s till you crested it. It didn’t seem to matter if it had 2k or 10k behind it. It got something like 10-12mpgs empty or loaded.
If I had to replace mine I would have another 06-07 with the LBZ even though the clean low mileage ones are priced higher than a top hat on a giraffe. Doing 75ish with anything under 10-12k it won’t even downshift out of 6th gear unless it’s a steep enough grade to warrant warning signs. It just builds boost and never loses any speed.

considering a 2014 or newer with a 6.2 and the same miles would probably be in the 40-50k range that’s not too bad. Sub 100k mile gmt 800’s bring good money because there aren’t many left. If that same truck had the LB7 it would probably bring mid 30’s.2001 Chevrolet Silverado 65K Miles 8.1 L Bullnose Crew Cab 4wd 340HP...

The only people who should be caring about residual value are the people who are buying a particular class of vehicle for a specific thing that will only last a set amount of time and will not be replacing it with an equivalent class of vehicle (like a commuter car for a job you're gonna ditch in a few years or a minivan you're gonna ditch when the oldest couple of kids are out of the house).
Value also means little to nothing if you intend on driving it until it's totally clapped out.
WTF?
degenerate at large
Wall of torque pretty much from idle. seat of the pants feeling is very similar to stock lb7 trucks I drove back in the day.
I was completely underwhelmed by my 6.0 2500hd It drank fuel like a sailor for not much more results than a 5.3. the 8.1 2500hd is a whole different animal; just Feels relaxed pulling heavy. Considering the 8.1 makes more torque at 1k that the 6.0 does at 4k that makes sense;
To many mouth breathers on facespace can’t put the engine size or at the least post a picture of it or I’m a mouth breather and can’t search the right criteria. A buddy is trying to talk me into a duramax

WhistlinDiesel moved Tennessee. You should sell it to him.
Huge derail, it’s turned into looking into a tow rig that’ll do anything I need and be parked until I need it. So, a friend of a friend has an 04 Cummins truck, auto, 4x4, 200k miles for 10k. The Cummins part yeah, the dodge part I’m meh about.
