Hey guys. New owner here. First time buying from GM/CHEVY. 2020 GMC 6.6 gasser. Been driving tundra whole life. Wanted a change, still have the tundra. Any idea of how reliable this truck can be or how many miles it can go? Also I heard the transmission is a reliable one for the 2020 model. Thank you. Sorry, I’m not too educated on GM products. Thank you
