I really like the Nemesis aluminum bumper. The only thing is that there is no place for optional lighting.

I went with his one, https://www.amazon.com/dp/B0FL1WC68F?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
had it inside the cab but the foil in the factory stopped it from working. Moved it into the ARE camper and works great…. It was cheap too!
I ran my rear Anderson along the drivers side. Used 4ga, attached to the main battery via a circuit breaker/solenoid. On the pass side I upgraded the Amazon switch/power, mounted in 110v location, with better wire, circuit breaker to the battery.
I went super cheap! The bedrug seals the bottom of the gate. For the sides, simple packing foam! Whenever I’m in the dirt I just place them on the vertical and shut the tailgate! Works real well.
