  1. Towing MPG

    6.2L 1500 on a round trip from Seattle to Los Angeles. Trip down without trailer, trip home towing 3200lbs Subaru on a 2500lbs car hauler. About 4mpg diff. Sent from my SM-G960U using Tapatalk

  4. Total system shutdown

    I had a 2012 Suburban do this. Would also fail to start back up after I shut it off right after this would happen. I had to short out battery to get it going again, or wait hours. Turned out to be corrosion at the negative battery cable connections to engine and body (not at battery). New cable and cleaned up connections fixed it for over 30k and 2 years until I sold it. Dealer paid under warranty. Sent from my SM-G960U using Tapatalk
  5. My dealer wouldn't. 2018 LTZ. Pointed me to another TSB that said hard shift from 1-2 in cold state is normal operation. I can find the TSB number if you'd like. Sent from my SM-G960U using Tapatalk
  6. The mounting eye on the performance series seems to be much beefy-er. Sent from my SM-G960U using Tapatalk
  7. Traveling by car, plane or train?

    High speed train travel in Asia is much better than air travel in US. Better scenery, better seats, better food, always on time, and safer. Interesting story on why the US has such lousy rail service, when it started with a huge lead. Car travel off interstates in the US is my favorite. Just all around a cool experience. Driving I-5 last week from LA to Seattle was not much fun. It really just weaving in and out of a long line of semis driving 55-60. I hate flying, except small airports.

    From LA to Seattle...so far the 6.2 is making easy work of it. Sent from my SM-G960U using Tapatalk
  9. Adding an amp

    Price range will determine a lot. I went NavTv M650-GM. It does what you ask and provides ability to Amp all 5 channels with out worrying about chime and phone leveling. There are cheaper ways too. Sent from my SM-G960U using Tapatalk
  10. Audio Help

    On my 2018, the dash speakers are a separate channel and play the door chimes and environment sounds. So replacing those can be important to matching the others. I also changed the door speakers from coaxle to separates and moved the tweeter to the sail panel. Huge improvment, but even more after adding aftermarket Amp. But that's were cost starts to balloon.

  11. Rear diff cover?

    19k plus miles of short commutes, long trips and towing. No leaks. I am not sure how quickly gear oil could leak through threads on two bolts, but I imagine it is quite a while. Besides the oil level sits below the bolts. Mine is most definitely not flat backed. Just as rounded as the factory. But everyone has to rights to their own concerns.
  12. Rear diff cover?

    B&M. I like the design and look.
  13. 0W-20 vs 5W-20

    So try an experiment: leave a quart or jar of each weight oil out by your truck on the colder nights. When you go to start your truck, see if you can tell the difference between the heavier stuff and the light stuff. For me 0 weight is just too much like water when "cold". At operating temps it more like a 30w, so I just don't think it makes a difference where I am and the narrower the range, the less modifiers to go bad, wear out.
  14. 0W-20 vs 5W-20

    I've been running 5w30 Amsoil for just over half the 19k I have on the truck. No problems. AFM still active and works like it always did. Temp here never gets below 20s though, except when up skiing. Sent from my SM-G960U using Tapatalk
  15. Spare Key Cost

    I think I paid $50 at a locksmith for a key (cut, programmed ) to hide on the truck. Not the fob, just key. But, mines a 2018. Not sure about 2019 keys and fobs. Sent from my SM-G960U using Tapatalk
