I'm curious to know about the off-road capability of GMC vehicles in general and how their 4-wheel drive (4WD) systems perform in different terrain conditions. As a GMC owner myself, I've had some great experiences with my truck's ability to handle rough roads and moderate trails, but I'd love to hear from others who have taken their GMCs on more extreme adventures. Are there any standout features or settings that make GMC 4WD systems particularly effective? How do the different trim levels compare in terms of off-road capability? Have anyone had any experiences with using GMC vehicles for serious rock crawling, sand dune running, or other forms of extreme off-roading? I'm also interested in hearing about any specific models that excel in this area, such as the Canyon AT4 or the Sierra 1500 AT4. Are there any aftermarket modifications or accessories that can enhance a GMC's off-road capabilities? I'd love to hear from fellow GMC enthusiasts and learn more about what our vehicles are capable of!
