Had my aluminum RCI Offroad Skid Plates (front, mid, transfer) and RSG Metalworks Flat Sliders with Top Plate installed at Saddleback Automotive (Costa Mesa/Orange County). The sliders are a big improvement and I'm currently running them without the trim piece from the OEM steps. If I had to do it again I'd order the same ones but with a black logo plate instead of raw stainless. The RCI skid plates are very well made but I need to do some investigating as I'm getting a noticeable vibration/buzz when stopped with the transmission in drive (no noise when stopped and in neutral). I assume it's either a bolt(s) that needs re-tightening (I checked them all right after the install and they were solid then), a KDDS hose making contact, or something in that vein. I opted to forgo the gas tank skid due to cost, but will add that in the future as the OEM gas tank skid appears to have taken a few hits already.
