Jeeperman skidz

I am looking into rocker skids and am partial to the Jeeperman series. I like the way they mount between the body and frame with no holes in the rocker itself. They also have a small "nerf" type bar to step with and give added protection. Question, does anyone have any opinions on them?? What are the exact differences between the Trail skids and Rock skiids? they look the same on the site. Can they handle the hard core abuse of rocks and hi lifts without rocker damage?? Also, anyone have any ideas on other skids that are as good or better, ,with a no drill type mount system that will move with a later installed body lift and a small step/protector bar. Especially no drill into the body. Thanks Tony
