Drove this truck 1,000+ miles up and down crazy steep grades through the Rockies and all over the Southwest pulling a 32ft trailer. This thing handled it like nothing. What a breeze to drive.

This truck is a beast when it comes to towing our 12k lbs fifth wheel. It is comfortable for the family on long trips and the tech inside is great!

We have a 2023 GMC 3500 and a 2023 Chevy Highcountry. Both brand new. One at 20k miles and one at 40k miles and both keep going in low power mode, shutting down exhaust brake option. Seth Wadley in Paul’s Valley has told us each time it’s a computer issue and needs to happen three time to each truck before they will cover it under warranty. The last time it’s made a large popping noise and left us 3 hours from home with a loaded trailer. We have one more time for it to occur to see if they will fix the problem. We have been Ram 3500 owners for almost 30 years. These trucks have more power and would like to continue to work with them but we feel vulnerable going across the country. Cannot rely on the truck. That’s 180k investment that you can’t rely on….

Just purchased a 2024 GMC Sierra 3500 for the whole purpose to pull our RV. Problem exist where the GMC errors out and disables brakes while driving. Inconsistent behavior. Always connects and remains active until something happens that it senses an issue and disables the trailer brakes. Odd that it reconnects the brake when vehicle comes to a complete stop (0 MPH) and/or put into park. GMC is blaming the brake actuator manufacturer. However, my RV worked fine on my 2022 GMC 2500 with no errors. GMC is basically saying it’s not my problem and produced a bulletin which pretty much blames the brake actuator simulator and says they are clean. I argue there are probably others with the same issue using an electric to hydraulic brake system. I also argue that to put this bulletin out after my purchase and my issue is bad customer service and support. If they don’t work with all third party manufacturers they should say that up front. So if you want a truck for pulling RVs without conditional parameters that are not publish, look for another truck. I gave a 3 because other than this trailering brake issue the truck performance is spot on. It’s a shame their engineers are ignoring this problem and left me to work around.
