I just got a 2020 RTL- E and am really enjoying it. Lots of features to figure out. I was about to buy and install a "Pop & Lock" for tailgate (a $100 add on) However after discussing it with the product rep. It seems my truck already has one from the factory. However, it comes from the factory "disabled" for some unknown/crazy reason. You have to go to your panel screen, find the "settings" menu, find "vehicle settings", scroll until you find the "tailgate settings" and "enable" the locking capability. Works like a champ now! Not sure all models have it, but the RTL-E does. Drive safely!
