2020 Ram 1500 common issues/ advice appreciated

I’m about to pull the trigger on a 2020 CPO Ram Big Horn night edition with the 5.7 Hemi. This will be my first non GM vehicle and am completely new to the Stellantis world. What are the common problems/issues that I should be on the look out for?
Thanks in advance!

Edit - suggestions for a hard tri fold bed cover is welcomed too.
