Good Luck on getting through to Uni-go. I have been trying since the begginning of February. I have even talked to the rep in Texas and in Colorado. Those two reps have never got back to me. That's why I went out and fabricated my own hitch. I will post some pics soon. What I have learned is Uni-go moved from Ohio to Florida and now that they moved no one seems to be able to get in touch with them. I have to say they have about the worst customer service of anyone I have ever dealt with!!! Have no idea how they stay in business, or maybe they are not in business??? Good Luck!!
