Nice design! Similar to mine

I like your philosophy.
i need to update the rack build, it's changed a bit.
I sold my Hella 500's and ditched the 550's in favor of HID's
Rewired the rack to switch between 2 and 4 lights via wireless remote control. Custom wiring harness between the bed cap and rack tray using 6 pin Amphanol threaded military electrical connectors.
So far the rack has been super durable, holds the Hi-lift without issues or noise, good place to strap down my dry bag for camp garbage, so it doesn't smell up the bed /cap, 101 uses, I love it.
