You need a Faraday pouch for the Fob. I take the key with me but I leave my Fob in the truck when bicycling and kayaking so the fob isn't lost or ruined if it gets wet. The pouch prevents the Fob from communicating with the truck while the pouch is sealed. I have the key, so I can get back into the truck when I return. https://www.amazon.com/Todoxi-Protector-Blocking-Security-Protection/dp/B082WGDRR5/ref=asc_df_B082WGDRR5/?tag=hyprod-20&linkCode=df0&hvadid=416694464775&hvpos=&hvnetw=g&hvrand=15386290623695121476&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9015854&hvtargid=pla-896807912066&psc=1&tag=&ref=&adgrpid=94693386675&hvpone=&hvptwo=&hvadid=416694464775&hvpos=&hvnetw=g&hvrand=15386290623695121476&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9015854&hvtargid=pla-896807912066

You weren't clear about exactly which alerts you're referring to. There are several; forward collision, lane change assist, cross traffic alert and some other minor alerts. I can't think of any reason a person wouldn't want to know they were about to have a rear end collision or back into the path of a crossing vehicle or change lanes with another car in that lane. All good safety features in my book.

I'm like you. I really liked the seats in my 08 2500HD better than those in the 2020 I have now. They were cushier to sit on and thigh support was a little longer. However, they weren't heated and cooled like the new seats and I find that I can drive long distance in the new truck without problems. I was a little worried at first that they would be uncomfortable when used for long periods but they've been fine. That said, I would still rather have a softer bottom cushion. The front seats out of a Ford Raptor would be perfect in this truck but that probably isn't going to happen.

Uncomfortable how? Too hard, back support not good, insufficient thigh support? How is it different than your previous truck?

Hard to say. The 6.6L is the standard engine on 2500HD's and is included in the base price. Ford only offers the 7.3 L engine as an extra cost option and includes the 10 speed trans with it. If the 10 speed does become available, I'd look for it to be an extra cost option as well.

I'm getting about 500 miles per gallon of DEF towing an 8000 lb Airstream trailer. The DEF gauge works well and shows about the right amount of DEF over distance traveled. It appears that the newer diesels; Ford, GM and Fiat Chrysler all use more than prior years to meet more stringent emission requirements. We're not alone.

I think all GM pickups use American Axles and have for the last twenty years or more.

Locking gas caps can be defeated in a matter of seconds and offer scant protection if any. A locking fuel door just means there will be more damage to the truck when someone jimmies it. Make it too hard and they'll just puncture the tank, take what they need and let the rest drain to the ground.

He's driving a Duramax and the MBRP is DPF back only - not a complete exhaust system, There are no complete exhaust systems for diesels unless a complete delete is made. A complete delete is ultra expensive on the L5P, voids your warranty and could potentially give legal problems since tampering with emissions systems if illegal. They also won't pass emissions testing if you happen to live in a place where they are required.

Regens are pretty much imperceptible by the driver most of the time. You may occasionally notice a drop in instantaneous fuel mileage or smell the odor hot pipes give off but that's about it. I have a Banks iDash gauge that can show the soot level in the DPF and show when cleaning is taking place but I don't pay much attention to it most of the time. You'll get a message on the dash if there is ever a problem.

The radio antenna on my 2020 2500HD is shorter than the one on my 2008 2500HD and I think that's the problem. 25 miles is a long way for FM signals that are line of sight transmissions. Shorter antennas are less efficient and aren't going to pick up a strong signal when the distance to the transmitter is near the reception limit. I have a 2019 Ford F150 with a longer antenna and it does significantly better receiving distant signals. It does, however, scrape my garage door when passing under it - the Chevy does not. It's a kind of trade-off.

I originally missed the gas blurb.

Your fuel mileage seems too low for such a small trailer. I'm getting 12.5 to 13.5 towing a 30' Airstream that weighs 8,060 lbs more or less depending on how much water I have on board.

I posted a link below that gives a pretty good explanation for the types of steel generally used in exhaust systems. I think all car makers use 409 stainless on gasoline engine exhaust systems for durability and have for the last twenty years or more. Diesel exhausts, however, are not as prone to rust as gasoline engines and manufacturers in most cases have not made the switch from aluminized to stainless. https://www.dieselops.com/stainless-vs-aluminized#:~:text=OEM exhaust systems are typically,rust resistant as stainless steel.

They must be aluminized steel. I just put a magnet on mine, both the tip and the pipes, and it was hard to pull off. Stainless has only a mild attraction to magnets - these are definitely not stainless.

Mine seems to be perfect. I haven't found any defects so far and I'm pretty finicky about my rides. Best of luck with yours.

I like the idea of it and the appearance is OK with me. Can the battery be changed when it gets low or does the whole unit get pitched and replaced with a new one?

Ditto the above. I find everything works best if the ignition is off when I plug in the pigtail. However, I've never had the trailer brakes not work properly regardless of the DIC message. I just ignore the message if it says brake gain wasn't recalled.

GM's own release: https://media.chevrolet.com/media/us/en/chevrolet/home.detail.html/content/Pages/news/us/en/2019/feb/0205-silverado-hd-2020.html New Allison® 10-speed transmission matched with proven Duramax 6.6L Turbo-Diesel “The 6.6L Duramax diesel and Allison® transmission is a legendary combination in the HD truck market with proven durability and capability that our customers expect,” said McQuaid. “For 2020, we made the combination even better and upgraded nearly every driveline component. As a result, we will deliver all 910 lb-ft of torque to the ground in first gear.”

The above example may be true, I don't doubt it, but it doesn't negate the fact that 2500's also deliver the all of the torque in first gear. 3500's are rated to tow more weight than a 2500 and thus a bigger ring gear. The reason prior models limited torque was to save the transmission - not the rear end. The transmissions used in both 2500's and 3500's are identical. There is no need to limit torque for one and not the other. Give us concrete proof that 2500's limit torque or get out of Dodge!

I don't automatically trust what I read but multiple articles say the same thing. I gave but one example from a widely respected source. Why should I believe you know what you're talking about? Show us the proof of your claim?

Where did you get that information that 2500's are torque limited in any gear? That goes against everything I've read about these trucks. Below is an exact quote from Car and Driver Magazine: "The optional engine remains the largely carryover 6.6-liter Duramax V-8 turbo-diesel—445 horses and 910 lb-ft—but is now mated to a 10-speed version of the excellent Allison automatic gearbox, up from the previous six-cog unit. The additional gears helped allow GM's engineers to lower the HD diesel's axle ratio from 3.73:1 to 3.42:1 to reduce engine speeds for a quieter ride when cruising. Although the Duramax falls short of the Ram HD's available 1000-lb-ft rating, the 10-speed combined with stronger drivetrain components allows diesel Silverado HDs to utilize their full amount of twist in first gear, unlike the previous models, which electronically limited the diesel's torque outputs. Among the myriad upgrades are larger, one-piece driveshafts and stouter axles with huge 11.5-inch ring gears on 2500HD models and full 12-inchers on the 3500HD". https://www.caranddriver.com/news/a25384331/2020-chevrolet-silverado-hd-2500-3500-photos-info/ Many other sources say the same thing.

The 2500HD's are not torque limited in any gear as has been stated above. The 2500HD's start from a stop in second gear in normal driving mode. They only start in 1st. gear when in tow/haul mode. That makes sense because the low 1st. gear is overkill when not pulling a load.

128 gb is supported and is what I'm using.

No special format needed. Just put your songs into folders - about 125 songs per folder works well for me. Name the folders so you can find the type of music you're looking for at any particular moment. The infotainment center will read and play the music on the USB drive when it's inserted in a USB port. I use the port in the center console and close the lid. You're ready to go at that point.
