Been doing a little more looking around on this - Hefty Fabworks has nothing currently listed and White Knuckle Offroad has nothing currently listed. The ADD rock sliders just bolt in where the stock side steps do, so I don't feel like they will hold up to a lot, plus there's no skid plates on them. The RPG rock sliders bolt to the frame and to where the stock steps do, plus they have skid plates, so they should work well. The KHC rock sliders bolt to the frame as well as where the stock steps do and have skid plates, but I don't like that they don't have the kick-outs at the back like the RPG ones do.
I'm thinking at this point RPG is the way to go.
