Oooooh, I've always wanted one of those, but I agree. Not worth $170. I jut keep it in the hitch and take it out every few months to grease. My plastic compartments are filled with other odds and ends.
I wish there was a nice place to store jumper cables and a tow strap. I have flares stuffed in the right rear side compartment. I used to be able to jam cables in the upper rear compartments on the LR3 (which had two full size compartments). But with the LR4 having only one large compartment and one half size, I'm limited.
