David,
I have the Kaymar on the rear with the tire carrier and overall, I like it. Its Heavy and yes its often a pain to open the tire before opening the hatch, but I like it. First, something about a "Real" bumper just makes sense. I can back into a lot of crap without worrying about it verses the expense of having to replace all that plastic. Also, it looks great. I also always worried about needing to get to the spare under the truck is I was off road sitting in the sand or mud. The logic of having a problem where the truck is sitting at its lowest and then having to retieve the spare from under the truck just seemed silly. The tire hanging out there gives the truck a whole different look and is really what did it for me.
I haven't done anything on the front yet, I'm hoping for a new entry into the market. For me, the ARB is currently just too large. I like the other bumper that they make for the LC200 without the brush guard, but its not available yet. Anyway, thats my 2 cents. Good luck.
