thanks for all the input guys. great info in this thread.
For the bumper I was leaning toward RTE, but then found a local & used ARB. The price was right and I couldnt pass it up. I picked it up this weekend and put it on. it looks good, we'll see how it performs over time and I'll consider an upgrade if needed.
here is the ARB on the rover
Now for sliders. I'll investigate a couple of the local makers, and also have a friend who has done extensive metal work. he made his own rock crawler - from scratch. I may recruit him to make some sliders for me. Keep the comments on this stuff coming, I am learning a lot and really appreciate the group knowledge.
