My previous EV experience is with a Model 3 and a Model Y. When you were charging those, you generally couldn’t tell. They are silent unless you just got done driving in the Texas summer and instantly plugged it. Then a fan may come on during the charging.

With my Sierra, it will kick on a fairly loud fan when I’m charging in my garage overnight. The truck isn’t warm when I start charging, but throughout the night it will get warm and warm the area around it. I’m charging at 9.6kW so not even the max power.

Finally got around to testing out airflow on the bento box. Or should I say lack of airflow.

Currently have a 120mm fan on order to pair with a community mod. Hopefully that will actually move air.

My truck was a courtesy vehicle with 4500 miles on it before I leased it. My capacity screen said 100% last calibrated X miles ago which correlated to the mileage on the odometer. On my Model 3 you had to drain to around 10%, then charge to 100% so I figured the Sierra was similar to that. I travel back and forth between CO and TX usually when I arrive, it's at 10%, so I let it set for a while and then charge to 100%. This last trip back, I arrived at 10% as normal, but my wife had the charge cable connected to her car, so I decided to wait until the next day. I decided to charge to 80% instead of messing with trying to calibrate. Then later when I got in the truck to go somewhere I noticed the battery calibration screen said "0 miles ago"...still at 100% though which I kind of feel dubious of.

so TL;DR - The truck will recalibrate when it feels like, or it may be sitting at 10% for 10-ish hours did the trick.

I've been trucking my CPAP back and forth with me when I travel between Texas and CO. I've been wanting to get a 2nd Airsense 10 for ages but considering I got mine a few years back when they were fire selling the Card to Cloud machines for $299, it just kills me to pay $499 for extra functionality that I'll never use. I found one on Craigslist that had been listed since mid April. When I messaged they messaged back quick, not very common for Craigslist. The woman said, she tried it, couldn't stand it and had no use for it so she'd rather have $100. I plugged it in on site, and true to her word, it had an entire 16 hours on it. One less thing I need to worry about now.

For background, I've been driving a Model 3 since 2018. Never had an issue with the car and loved it generally. Just won't buy another Tesla until they dump the current CEO. I drove a Sierra 1500 to the Tesla store to trade in on my Model 3 so this definitely isn't my first truck...it's actually my 3rd.

With that said, there is definitely an adjustment going from something small like the Model 3 to something large like the Sierra.

Pros:

• Vents that don't require multiple taps to adjust
• Amazing range.
• So much storage, front and back
• So much leg room in the back
• I can see traffic ahead of me so much better
• Physical buttons for stuff you access often.
• Such a quiet cabin compared to my Model 3
• I have an actual spare tire! Unheard of nowadays
• The range display is way more accurate than my Tesla ever was. There's a reason most Tesla drivers just display percentage instead of range.
• It runs android and has an App Store to allow you to install the apps you prefer.

Things I wish were better:

• Even in sport mode, steering seems soft.
• I'm a data nerd and the amount of information about charge statistics, usage statistics, etc is not on par with what's available from my Tesla.
• The base software is not up to par with Tesla either. The Apple Music client stops randomly. A Better Route Planner is disabled because it says I need to prioritize it, but never gives me an option to do that.
• When home charging inside a garage, this truck generates a lot of heat. Something I've never dealt with before.
• Even though it geofences the garage door openers, why not give us the option to automatically open them like my Tesla does.
• I have the base stereo and it's just meh.
• You can leave the truck "running", but I really wish it had a dedicated dog mode.
• Still no phone key. I really hate carrying around a key fob, especially one this size.
• The charging network integration in the app is not great. It's a task to figure out when to start charging sessions from the GMC app or the network app. It's also a task to figure out when you should get a membership to whichever networks.
• The onboard routing doesn't have a way to say "don't use this charger again" when you encounter a crap one.

* there is a thing called a passenger and it knows when they aren’t wearing a seat belt so why can’t they operate the nav/radio/streaming while I’m driving?

Things I should have considered more:

• Highway speeds affect less aerodynamic vehicles a lot.
• This is a heavy truck and you have be cognizant of where you're parking it. This truck is right at the high end of lbs/square ft of a standard concrete foundation.
• I'm leasing my truck so I didn't want to spend a lot on my tonneau cover. I didn't realize how loud that flapping would be inside a cab that is generally so quiet.

When I was originally looking for a vehicle to replace aging Model 3, I was relying on ABetterRoutePlanner's vehicle comparison tool that displays the times that a trip will take in different EVs since this was the main use of my EV. Because of the charging speed and battery size, the Sierra EV (Extended range) was one of the vehicles rated the least amount of time. In reality, that didn't pan out. Looking back, the Lyriq (my other choice) probably isn't as slow as they showed it to be. ABRP assumes that a 325kW Tesla charger will deliver a 300kW peak speed to my truck. I've got a 2 year lease on this truck and I do love having and driving a truck, but given my use cases, I probably should have picked a more efficient vehicle. No fault of the truck, just my excitement of having a truck again.

My adult daughter brought home one heck of an infection from her classroom. I ended up getting it a few days later. It's been three weeks now and I'm finally feeling in the clear. This was even with a steroid and antibiotic. Constantly blowing my nose and and a dry hacking cough throughout the day. Completely miserable.

But at night it wasn't half bad. The only setting I changed was to max out the humidity on my Airsense 10. It's amazing to me at how well my cpap will keep my nose open through the night. By morning I could have a little bit of time with a productive cough. I can't imagine what this would have been like without a cpap. Well, actually, I kind of know because my daughter did not get a good nights sleep for about 2 weeks.
