I bought the Yakima swingdaddy yesterday. Sadly it does not clear the spare, so even though the bike rack swings out away, the spare does not clea the arm with out a 3 inch drop. i am thinking of having an extended receiver welded to the bottom of my factory receiver. That should give me the clearance. i love the rack, adn I got it on amazon for $150 cheaper than the Thule which looks like it would clear.
Thule swingman from amazon: Amazon.com: Thule 9027 Apex Swing Away 4 Bike Hitch Rack: Sports & Outdoors
Yakima Swingdaddy form AMazon: Yakima SwingDaddy 4-Bike Hitch Mount Rack (2-Inch Receiver) : Amazon.com : Sports & Outdoors
Well now that I look at it again it must have been a daily deal. The swingdaddy is $150 more than I paid. Glad I bought it when I did.
