Have any of you used anything like this? I'd like to take my bike with me ('02 GSX-R600) when I get home and drive cross country. The Class III hitch's on Quadratec have too low of a Max Tongue Weight. None of the little cars Ive had ever towed anything so I have no clue about hitches. What can I get for the JK that will have a TOngue Weight of at least 500lbs or so? And any feedback on your experience, either personally or witnessed about these kind of bike carriers would rawk!!
