My 2001 High Country did the same thing. Sometimes they'd work, sometimes they wouldn't. Pretty sure it was a camera issue. Don't have the truck anymore to try different remedies.

The idea of a RAM with the Cummins/ZF combo intrigues me as well, but only with a dually and 50 gallon tank. Like you, my current truck has been great so far. Granted only a couple years, but no issues to speak of. I've always been a GM person, but my current Ford has been great. I had issues with 2 of the last 3 GM HD trucks I had. Since, the transmission issues have increased, the oil in coolant issue, and the sliding window frame cracks still make me skeptical on going back right now. Then, some people still go 100s of thousands of miles on any of the HD trucks from any brand and never have an issue. Get what you want, you can always get something else if you don't like it.

I'd let it ride. Good job, @Pryme!

I think the room and tech in the new trucks is great, but the powertrain is better and more reliable in the previous gen. The 2017-19 seem to be the sought after GM trucks. L5P with a genuine Allison is a sweet combination.

An oil analysis by Amsoil?

Good results! Thanks for sharing.

If the oil is changed at regular intervals or per OLM (also regular), it won't matter which brand that someone uses. Nor will it affect the potential for having an oil-burning engine. Simple, routine maintenance is all we can do.

Get you some real Rancho shocks and try those. Much different than the GM spec-built Rancho shocks that come from factory. Last truck I put on the Rancho 9000XL shocks. They are adjustable, but the 5000 and 7000 series are good as well.

The seats on the 2020+ trucks are extremely firm. The OP is not alone in this regard. I do not know of any complete seat replacement for these trucks. The hard seats and leaking rear slider issues are probably the biggest complaints of these trucks since they debuted. Ride is great, power is great, great features.

When changing oil, put in the required amount by the manufacturer, not what the dipstick says. Once this is done, then you have a level on the dipstick that you know is the true "full" mark.

Ford figured something out with the 23 update. They absolutely ride much better than previous generations. I went from a 2021 Silverado 3500HD High Country to a 2024 F-350 Lariat Tremor and the ride is much better. I was thinking tires, too, but others that have been in a 2023 or 2024 Super Duty say that they are smooth as well. One thing is sure, the GM seats suck and get worse with every generation or update.

The seats on my 2020+ HD trucks were extra firm. Now the seats on my Super Duty Lariat are very comfortable. Reminds me of my GMT-800. Even on longer trips, they aren't an issue.

The GM seats are super firm. To my surprise, they don't give in after several years. It was the first thing we all noticed when I test drove a Super Duty. Those seats are very comfortable. Reminds me of the GMT-800s.

Maybe in another decade or so........ That sucks. After having several leaky windows and replaced the last one with a solid window, there was still a slight drip. No where near the streams on each side from the cracked slider frame though. I now believe the cab structure at the window is weak as well, contributing to the window frame failures. I'm done with these trucks and their crap designs until they change it. Going on 6 years and it's still an issue... Guess it's like the AFM/DFM lifter failures that they ignore, too.

I can't answer about the 24 differences or improvements, etc. I can tell you the difference in Ford and GM seats. The Ford side and bottom bolsters are thicker, plusher and softer. The mid (seat and back) is very similar between Ford and GM, though Ford is a touch softer. The newer seats in GM are not near as comfortable as the GMT-800s. The ZR2 could indeed have more padding, or it could be just a different stitching to look that way.
