I personally don't care for those "one rhino step that goes in the hitch reciever". I think a few people on here have them and I haven't liked one yet. I guess it is a personal opinion. My opinion is I would rather have nothing rather than that hitch insert step.
On the flip side, I would love the T&H single-pipe rear. The black is cheaper than the chrome and may easier to paint. Which I think is a must with your painted bull bar. I say go for it, after confirming with T&H that it can easily be painted.
