IMO, he should have been able to find it for both 2019 LT and LTZ 3500 crew. The post above is copied from the order guide. Z71 shows up in the 'exterior section' rather the 'mechanical' section. Z85, the standard suspension, show up in the mechanical section. Don't know it the codes are located in the same type of sections on a dealer sales screen EDIT: Z71 also shows available for a 2019 3500 crew on the website 'build-and-price' at cheverolet.com
2019 3500 Silverado Looks like Z71 availability depends on trim. For the 3500 crew cab, from the order guide: Z71 Z71 Package, Off-Road, (Requires 4WD model.), includes twin tube Rancho brand shocks, (JHD) Hill Descent Control, (NZZ) underbody shields.

Brakes on the 2011 and newer HD's are huge improvement from the earlier GM HD's. This link is old but discusses the differences. http://www.maxxtorque.com/2010/12/2011-duramax-lml-review-built-to-tow.html
redwngr replied to ArgentPower's topic in 2000-2014 Silverado & Sierra HDDo the lights still flash when the horn is set to off?
redwngr replied to Ke32's topic in 2015-2019 Silverado & Sierra HDI switched back to a 2500. If ride is a concern, get 18" instead of 20"s (I learned this lesson when I was trying the 1500's for couple years). The 2500's on 18's, when empty can be aired down to greatly improve the ride ( and tire wear). The pressure for the trucks rated load is much higher then what is required when running empty. I pulled this trailer from Port Huron to Phoenix and back with the 1500 5.3 NHT. Travelled interstate. It never had problem losing speed on the grades, but it was almost always in 6th. Sometimes as low as 4th and not more than 15 minutes total in 8th (when at interstate speed). Biggest annoyance was the short fuel range doing this job. MPG was always in high single digits so range about 200 miles. Often, due to filling opportunity locations, it was necessary to stop for fuel well before 200 miles. In this situation, the extra 10 gallons that the 2500's carry would have made a huge difference. The trailer wasn't/isn't particularly heavy, but the frontal area made the 1500 work. The suspension on the 1500 makes the combo sort of float when the road had rises and dips. The 2500 with same rig on similar road conditions always feels under control. Similar floating/under control comparison pulling our boat -- but it gets towed twice per year, for only about 30 miles. Despite all the stories about what works (or doesn't) for me, or anyone else, the answer to your 1500/2500/3500 question STILL depends on 3 things. -- how heavy -- how far -- how often
Mine shifts at lower rpm when the engine and transmission warm - perhaps that is what you are seeing? After warmup. and at gentle acceleration it has shifts at about 33, 42 and into 6 at 53. Once shifted it will hold the gears to lower rpm then the shift point (if throttle application remains 'gentle') I'm sure they are programmed to hold the gear lower than original shift point to avoid excessive 'hunting' for the correct gear.

He's not looking for weight rating -- he's looking for actual empty weight to set lower pressure to improve ride and tire wear when doing daily driver duty.

Don't forget to divide by 2 to get tire loads - these are axle weights. Make sure the numbers from michelin are for the correct load range to match the tires on your truck. Or go to a truck stop with a scale and have front/rear weighed separately. Those with 2500's can get the TPMS settings lowered by the dealer.
