And by the way the AT4 premium package has nothing to do with the 5th wheel prep package. I might be wrong, but I didn't think the AT4 premium package was a dealer installed item.
Wouldn't do anything but GM OEM. Installed them on my 2025 HD. GMC PRO. The fit was perfect, and the install was a piece of cake, too bad I can't find them for my 2020 dually.
Just finished wiring up the switches that came installed in my "25" PRO HD. The hardest part was getting the 10 ga. battery wire through the firewall. If you're going to hook up an accessory up front somewhere pull that power wire through at the same time. Also don't forget to pull a small pull string through for future use.
Anyone find a quality SS. exhaust tip for our 6.6 gassers? Must be bolt on, 10-12 inches long angle cut and rolled I have looked every ware. Any help would be greatly apricated.
It's good that some people have a use for them, I was lucky I could order my 2020 GMC 3500 DRW. without the multipro. With a fiftwheel or my gooseneck horse trailer they are useless. Good luck with your install.
