Rear Sway Bar Question

Adding the rear sway bar cured the wheelie launches (dropping 0.1-0.3 off 60ft) and tremendously helped hard braking sway with the camper.

Sounds like a win.
What bar did you put on the rear of your truck?
Nice launch pic! What are some numbers for the nosy folks that like that kind of stuff?
