So, I purchased a Putco Blade for my 2019 1500. when it arrived, I thought an hour and it's done.. Then I realized the bumps on the end of the bed where it would normally be stuck to. I decided to make a "rail" for the light bar to sit on and have a smooth place to attach to. I used angle aluminum cut to length and attached it under the smooth level plastic on the bumper. It works exceptionally well and was very easy.
I made sure the tabs I made pushed the aluminum all the way to the bumps on the bed and there is plenty of clearance for the tailgate to open and close with zero issues. The tabs were installed under the plastic so all you see are the screw heads on top of the plastic, I should have bought black screws, duh. Just being lazy, and a little nervous about the sensitivity of the electronics of this truck, I used the Curt adaptor for the wiring.
