I'm a few miles from the north shore of Lake Erie -- so we should have similar weather.

Have you enabled the seat memory features in settings? There are a bunch of auto features than can be enabled/disable/modified in the trucks settings.

If the 2019 is a k2 (LTD version) it will not cross over if the 2019 is a T1 - new version, it will.

Service advisers 110 kph argument is bullcrap and they (should) know it. The dealers management and GM proper should be embarrassed that any service adviser said that. If you end up talking with GM Canada's Oshawa office, ask how fast they need to run on 401 from Oshawa to Pearson airport.... Or when running north to Barrie and on to cottage country... If 100 kph was real, why is the trucks speed limiter 160ish? What happens if the truck is taken to US and run on one of the 80 mph (128kph) speed limit interstates or the 85mph (137 kph) locations? Fwiw ran mine for many miles at 80 mph or above while on tour last summer. Silky smooth at all time. They also know that there is not a different version of the differential for US vs Can.

Depends on where the battery lives and how it's being used. (heat is harder on them than cold -- as long as they are charged) There has been a large fleet of batteries around here - cars/trucks/motorcycles/garden tractors/farm tractors/forklifts/backhoes/excavators/combines.... With my usage and location I expect battery life to be about 7 years and I don't change until they give an indication they are dying (like unusually slow cranking) Despite my 'expectation' some only last a few years and some go longer than 7 (which is why I don't change until the battery indicates there may be an issue. If a battery has ever been deeply discharged but is able to be 'revived', it's life will have be shortened. (of course, 12v batteries cannot always be revived) I wouldn't change it unless it's giving 'warnings'. Whatever is in it seems to be giving good life -- why not repeat when the time comes?

Have played with the equalizer settings? Makes a big difference on my '23. Of course the type of music and the source format matters too

Swap 2 tire locations to see if the problem moves so you'll know if it is a sensor issue or a truck side issue.

I'm not going to suggest which to buy, but have some info and things to consider. Yes, they are both LZO. 2023 model year was first for LZO in pickups. (full size suv's changed for 2025 model) If it's only gonna pull the boat, how many miles per year? Are the trips with the boat long? Will the extra features be a benefit for those miles? 3.0 has a 5 yr/100,000 mile powertrain warranty When updating, I sometimes like to look at cost per mile. $10,000 / 66,000 miles is $0.15 per mile.

What cab trim? If it is rear seats and usb ports for the rear, they will be power only. What dashcam make/model?

16-NA-361 1..2

How many models of battery does Johnson controls make? How about Penn, do they make more than one model? How about Exide? and so on... Any chance that the models 'branded' for one company are not the same as the ones 'branded' for another company, even though they are produced by the same manufacturer?

Yupp, I knew that. But it's usually the next question asked in these threads. It's your truck. Feel free to ignore the information

^^this^^ One of my questions about performance claims is.. "How much time do you spend at wide open throttle and between 4100 and 5600?" More than one thread has posts from owners that have installed CAI's and then found the intake air is warmer. I guess they like the look when parked with the hood open?? .

Absolutely. Especially if the area around the filter is dirty from seepage or from road/field debris.

It's now had bulk DEF added 4 time (and is currently showing about half) Average def mpg - 1380 I don't have the last fuel fill added to graph. This 28,000 miles averaged 29.2 usmpg

Update on my 1500 history: I ordered 15 6.2 8 speed double cab. It was built early enough after change over that they weren't putting max tow and tow mirrors on 6.2's 8 speeds yet (at the time tow mirrors only came if max tow was added) I'd been running trucks with tow mirrors for 10+ years and missed them. Decided I couldn't stop the extra price for premium fuel. Ordered a 16 crew cab std box 5.3L 8 spd max tow (so tow mirrors) I track every fuel fill. Doing my tasks, both trucks were always about 20 usmpg. Doing the same job, my '21 crew std bed LM2, with tow mirrors, gave 26 (life of vehicle - 35,000 miles) Decided I wanted the the new interior and also that I didn't like the T1 generation tow mirrors. Ordered the current '23 crew std bed LZO. Regular mirrors instead of tow mirrors. It's giving a little over 29 life over 29 life of vehicle. About 29,000 miles so far.

If it has stop/start is uses an AGM battery If it does not use Stop/start it uses flooded. Sierra and Silverado use the same ones.

Sealed engine compartment? Air coming thru the rad and coolers washes thru the engine compartment. Since it want thru the coolers and rad, and then washes over engine components, it will be warmer than ambient. Some of this air will enter the opening at the top of the s&b filter box. The blended air must be warmer than the ambient air feed via the stock routing. Imho, this is the reason you're seeing hotter intake air. Gotta admit it seems odd the S&B video claims 3 sources of air to the filter box if there are only 2.

Any update? Full tank mpg numbers?

I haven't looked at one (which is why I checked the video) The headlight reference is from the S&B's video for about the 5.3 and 6.2 -- and from S&B's website. Are you saying the headlight is sealed or the bottom of the filter box has no openings in that area? Video doesn't show the area, so my guess was the filter box has an opening to the area behind, but not connected to, the headlight.

With the stock system, cold air coming thru the trucks front grill flows up thru the slotted area circled in green, the travels to the round area her hand is over and flows down to the connection to the filter and intake. S&B takes air that way, but blends it with cold air drawn from under the hood at the slots circled in yellow at the filter box and air taken from near headlight. Of course the under hood air has travelled thru the radiators.... Picture is from S&B video for 'cold air intake for 5.3 and 6.2' https://sbfilters.com/products/silverado-sierra-1500-intake-75-5128

The diesel supplement to the owners manual also says to use the block heater when below 0F / -18C. Fwiw, the 3.0 starts fine, unassisted, below 0F. I've not even unwrapped the block heater cord. Block heater is standard/included with the 3.0

Probably too late to help, but the 2024 2500/3500 GMC owners manuals says for gooseneck or 5th wheel that pin weight of 15 - 25% of trailer weight 2024 3500 DRW Crewcab 4wd 5th wheel/gooseneck ratings Longbox srw for comparision

Hmmm. So now I'm curious how a camera knows how far away the vehicle ahead is? Can't be width or height, because of course vehicles aren't all the same size. I was under the impression the lidar (or maybe radar? or ultrasonic?) gave distance and the camera determined if the vehicle detected was in the same lane.

Is there also a lidar in the grill that is used by adaptive cruise and by forward collision alert?
