Well, with the SLT it is easy, just look at the door and you will see "2500" or "3500". Since the "AT4" or "Denali" replaces "2500" or "3500" emblem on the door panels for those models, how can you visually tell the difference between the 3/4 ton or 1 ton? I understand there is an additional leaf spring on the 3500 but is that the only way to tell?
