Sway bars versus RAS versus SS…which one did you choose/why?

I have posted before that the weight should be supported by your leaf springs and fine adjustment by air bags. My truck came with anti-sway bars in the Camper Package, so I never drove it without. My bar extends to the front of the axle and does not in interfere with the spare in any way. The only downside of the bar is articulation in off-road use - I used to lift the rear wheel on the truck when on rough "roads" without the TC and was glad I had a limited slip differential.
