I can't comment directly, but I did install a set of Amp Powersteps on my previous truck (2009 1500), and I can't imagine it was much different. Overall, the installation went fine, and I was impressed with the quality of both the kit itself, and the instructions. I see the installation is a little easier on the 2019, as there are factory studs to hang the link arms from (previous versions had you installing backing plates and threaded inserts in the rocker panels). My only suggestion would be to use Loc-tite on the screws that hold the end caps on to the steps themselves... a couple of mine backed out over time. The wiring is much more simplified, as well - mostly done through the OBD-II port now.
My only complaint was with the lights that come with it. They're a little on the cheap side, and the 3M VHB tape as a mounting solution could be a little better. There was a post here somewhere about upgrading to some after-aftermarket high output LEDs that utilized a magnetic mount - I'll see if I can find that. I want to put those lights onto my truck with the factory (non-lighted) Mopar powersteps.
If it's any consolation, the steps are just over 9 years old, and still working just fine - even though I no longer own that particular truck.
