Nope, but I was aware of the new bulletin because of looking at it during another discussion on another forum.

UI-Bulletin-193d-2.pdf (gmupfitter.com) Page one shows they've included 2024 HD instructions 2022i for 1500 and 2024 for the HD's is when they were 'refreshed' and have electrical system was changed to Global B

IOK is also not optional on the trims that don't have it standard. (some years they have optional audio upgrades orderable for some trims) From 2024 2500 Cdn order guide Even with IOK, the trailer camera provisions are still optional, except on ZR2

Build and price often doesn't get updated immediately. Changes are few, so if you want to order one, 'design' it as a '24 your truck and then call or sit with your favorite dealer.

Do you have the trailer plugged in when you are trying to get the camera to work? With my '21, I learned that the trailer needed to be connected. Don't know it this is true for the Global B (refreshed) trucks.

Should be on the glass, where part number etc is located. They are printed for viewing from the outside. (yes, they are difficult to see) Windshield - bottom corner on pass side Drivers door lower rear of glass Driver side passenger front lower corner etc Windshield a front doors are 70% Rear doors are 20% The number is what % it will pass. Auz may have different rules about tint.

2023 2500 factory offerings. (retail and fleet versions) Of course you can change diff ratios, but 4.10 wasn't offered in 2023 I don't know for sure, but 20 - 22 likely they same. 4:10 may have been last offered with the 6.0 -- 2019 and earlier 2023 2019 Dmax and 6.0 both had speed transmissions.

What's an FT4 engine? What's any of that got to do with the guy towing a and working it hard enough that it gets 10 mpg pulling a camper down the road?

Do both coolant reservoirs still have the correct amount of coolant? Any evidence that there might be a leak between of 'boost air' between the turbo and the intake? DIC has pages for fuel filter and air filter condition. Might have to be 'turned on' in the settings menu to be able to see them

More fuel burned means more def required to process the NOx The fuel to DEF ratio should stay at about 2%. 100 gal fuel to 2 gallons of DEF If it's using a whole tank -- 7 gallons -- for 93 gal fuel, that would be 7.5% -- From 2024 6.6 diesel supplement The 3.0 has a smaller DEF tank

Are you looking for higher speed for accessories or engine warming in winter?

The technician probably has all this. https://www.gmupfitter.com/wp-content/uploads/2021/06/UI-Bulletin_82h-1.pdf

Any chance it's the road it's being driven on? Without supercruise, some roads require much more correcting than others.

If dry and dust-free is a requirement / issue the stuff should be in the back of an SUV. Even if the tailgate doesn't leak there are still holes in the bed.

Hard to find one of those in todays pickups...

I wondered if someone would comment about that! It was what my local FM 'classic rock' station happened to be playing...

GM recommends use of a block heater at or below below 0*F for the 6.6 and 3.0 dmax engines.

He must have an aftermarket OBDII port reader. The truck displays do not indicate soot level, and they do not indicate when it is in 'normal' regen.

LZO did make it into the 2025 order guide for 2025 Yukon -- but with 'Late Availability'

I don't use AA or CP (almost never) Anyway, in the 2nd picture there is a white arrow on the border between the big and small sections of screen. Pushing the arrow will expand the map to full screen. This arrow does not show up when the audio page is on the LHS of screen. When the map is in full screen mode, pressing the audio button (2nd from bottom in last pic -- those buttons can be moved, yours might not be in the same place.), it will add the audio page back to the screen.

When the switch was made, I was in high school. After high school I took mech eng. We had to learn to use both systems. After graduating I spend time in both automotive parts manufacturing and heavy offroad equipment design/test/development. Both industries were doing new design work in metric. Anyway, I generally use both. Speeds, distances, temperatures, weights are easy to use both ways. But is still detest using L/100km instead of mpg

I believe the Global B trucks (refreshed) use different sensors that the previous generation. 1500 changed mid 2022 model (so 2022.5 or 2022i) I traded a '21 1500 for a '23 1500. I kept the winter wheels I had used on the '21 --- but found I had to get the new sensors. I'm not sure about tire shops, but at my dealer the OEM ones were cheaper that the universal fit 'aftermarket' ones they like to use. I quizzed them if they were quoting OEM. They looked up the OEM price and seemed surprised the OEM ones were cheaper. (not sure if that pricing difference holds true for the pre-refresh sensors).

Something is seriously wrong with the parts guy at your dealer. These are from the US Chev website accessories section Set for 2022 2500 LTZ Trailer tire sensors are different the the ones for the truck, so I copied both. $40 x 4 = $160 for a set of GM ones for your 2022 2500 Even if they were going to install the sensors, $450 seems pretty high.
