GM hasn’t used a heavy guage steel since the GMT400. When they changed to GMT800 platform, they significantly reduced the steel thickness to save weight. I could dent the box sides with my thumb. The bodies became an issue, the boxes escpecially. The 800 box rails were built / constructed in manner that it was difficult to bolt through. They had a tendency to crack in the front corners when running full racks. The GMT900 was the end of the road for me with GM. Eventually switching over to Ford first gen SD’s. The GM drivetrains were good. We had many GM trucks back then.
I had a long conversation with a GM exec, VP of marketing iirc, at a large showing in Michigan in 2003/2004. I told him the issues we were seeing with the bodies, and he told me flat out - “We don’t build trucks for working anymore. We sell more trucks in California alone, than all of Canada. They’re build to haul surf boards.”
Id like to see some of the aluminum SD’s after running heavy / awkward racks on a stock body.
Those GMT400 definitely had some heavy gauge steel and definitely more than the Ford brick nose from that period. Also GM did have some thinner sheet metal in the GMT900 and recall the long wheel base trucks you could see some rippling on the bed side. Having said that, I do believe the current gen GM truck have gone back to a heavier gauge steel and that issued have been resolve. Problem is those trucks are just so ugly...
Then the steel must be paper thin, the deflection by touch is crazy and it’s a much lighter feeling door than the Ford unless the Fords just use crappy hinges. I doubt that’s the case since this is straight from Chevrolet:
“The 2025 Silverado 2500 door skin is made of aluminum, a common material used for its lightweight and strong properties in truck bodies. Aluminum is used for components like the hood, doors, and tailgate to help reduce the vehicle's overall weight.”
I think it's a typo, the left front door part number is still 85873588, 2020-2026. That door is steel.

We had trouble with bed cracking in the GMT800's when we mounted boxes and racks on them too. But not the GMT900's, that bed was much stronger. The inner panels carried through on the next generation until 2019. Funny thing about the GMT900's, because the bed sides were so smooth with no creases they would ripple a bit.
So I did a deep dive into the parts, you guys are correct on material per the parts description attached to the number, but you’re incorrect on the weight. From what I find spec wise in the parts catalogs shell only weight for 2026 Chevy 2500 HD driver door is 32 LBS, shell only weight for 2026 Ford F-250 driver door is 35 LBS. The Ford door is heavier no matter how you slice and dice it.

I didn't say anything about the weight of those doors, but I am not surprised about the Ford door being slightly heavier. Aluminum is substantially weaker than steel, pound for pound, so the door guard beam in the Ford aluminum door has to have a lot more material in it to meet the applicable crash standards. Also, the Ford door is assembled with glue and rivets, which also adds a bit of weight over welding.
Seeing how many K2XX are all ready rusted through the lower door skins and rocker panels here in western New York I just have no interest in owning another steel body truck again. In 7-8 years your rocker panels are shot if they are made of galvanized steel here, the aluminum will still be like new.
His last 2016 Super Duty Lariat White Tri Coat Metallic truck was rusting through everywhere. Door skins, rear wheel wells, rockers. The truck was eaten alive in the span of 8 years by the salt. First bubbles appeared on the rear wheel wells when it was only 5 years old. Steel just doesn’t work well long with northeast salt.

We have mostly Chevy/GMC trucks at work. The only thing I can think of that I prefer on them is the fold down center console. The cup holders are an inch lower than the arm rest. I can't stand the hard plastic cup holders at the same level on the Fords. For anything more than a short drive the plastic becomes very uncomfortable to rest my arm on. It must not be a problem for most people because it's hard to find an XLT without a bench seat, even though the better seats are only a $500 option. I was going to order an XLT to get that option, but ended up finding a good deal on a used Lariat.

I agree with you, most dealers have their niche for lot trucks. The dealer I bought mine from seems to only buy loaded out XLT’s, so all the stock ones had the center console and pano moonroof etc. I was the opposite of you, went in to order a Lariat and left the same day with the XLT because it had just about everything I wanted.

This is true. GM really doesnt compete well in the service truck arena. Its Ford, Ram, then Toyota.
GM's buisness model, is pretty much duping people into owning them. A well educated, experienced person, doesnt drive GM. Theyre better than Kia sometimes.

Total anecdote but every guy with a recent model year Chevy or GMC pickup in my neighborhood fit that bill to a T. For some reason it attracts a certain personality type.

Just a quick note, the reduction in steel thickness was also accompanied by a change to high strength and advanced high strength steel materials in the panels. This allowed the "strength" of the panel to be the same but with a thinner material, which would also be less weight. What it doesn't help with though is corrosion, it will rust through faster.

Back in the '40-50s Dodge used to sell "Job Rated" trucks, i.e. they built the truck for the purpose required. There was a promotional/documentary video about how that worked which I found immensly fascinating and illuminating. There were about a million combinations - way more than today as far as functionality went - regarding engines, transmissions, front and rear axles, springs, rear ends, and bodies. And yeah, no A/C, power rear window or massaging seats were on the list.
They would have assessed the need and specified every part of the truck, including needing heavy/awkward racks.
Of course, today you can get a C&C and add whatever body that suits your need, but so many people think that a factory body with an off-the shelf rack should be able to do what you want. Well, what if you need to carry 2000# slabs of granite, or oversized insulating glass windows, or who-knows-what? Then you need a C&C with a body designed for your needs.
It's pretty long, at around 25 minutes, but this is the old Dodge video. I encourage any and all to take a look when you have a few (i.e. 25) minutes. It's a bit cheesy by today's standards, but fits well withing the time, and as I said, facinating:
If you want a crappy Korean car with an undimmable giant useless touch screen, by a Kia.
Firstly, I don't think Kia makes "trucks" at all (anything over 1000# payload). The parent Hyundai probably has several at least Class 6 trucks somewhere in their downline. Actually, a quick search of Google suggests they actually make a Class 8, though it doesn't appear that anything over Class 6 is available in the USA.
Secondly, what's this about "undimmable giant useless touchscreen"? We are on our second Telluride, and love the "dimmable giant useful touchscreen". Although honestly, I've never tried dimming it - it seems to dim all by itself satisfactorily.
