I have a 2025 Silverado double cab RST with the Duramax diesel. It has the standard tailgate and I've watched some videos on how to get the multiflex tailgate to work. I'm an electrican (among other things) and don't think I'd have a problem getting the wiring straight, I'm just not sure what years will fit my rig. I'm pretty sure the 2500/3500 gates are different sizes, but does anyone know if a 2024 or earlier will fit on a 2025? Thanks for your help...
