Pin weight is a big factor along with ensuring your rig is level behind the truck. I had the same issue with my 2015 Sierra, and, to a lesser extent, my 2020 DRW - trailer pin weight of 3,200+/-. I went with a FlexAir pin box with the 2015 Sierra, and it eliminated 95% of the chucking. It was too long for my 2020, so I went with the RotaFlex, and it did the trick. I like the RotaFlex much better than the FlexAir, as it is a simpler design, and you don't have to worry about adding air all the time.
Tomato replied to Laidback's topic in 6.6L Duramax Diesel & Allison Powertrain (L5P/MGM)I have one, and it is great for watching saturation level and regen status, among other things. I always try to let the truck finish its standard regens, even if I have to drive for a while longer. I have not needed to run a manual regen.
I had my pads replaced under the TSB, and they are now doing the same damn thing again after about 2K miles. To top it off, the dealer screwed up my outer rear rims when they reinstalled them and did not connect the front driver's side wear sensor. Idiots.
I made the decision to order a new truck. Stepping back to a 2500 gas this time, as I am just tired of dealing with DEF and all of the surrounding issues along with the stupid price we pay for diesel in Commie-Fornia. I sold our Fifth wheel and just don't need the DRW or the diesel anymore. Also, it will be nice having a truck my wife can drive when necessary. So...Does anyone have the scoop on the new Forest and Hunter Metallic paints? Color was the biggest challenge when I ordered my 2020, as I wanted something close to my 2015s Iridium. Some of the new colors were nowhere to
Good luck on it. Mine would do that with my 5th wheel when a sensor would lose signal (40' 5er too long for signal) before the dealer did a flash update. After the update, a sensor would still go in and out, but it would not trip the whole system and cause the service TTPS system message.
