The Yakima website's fit guide says it will fit, but it won't!
Test mounted the SwingDaddy today on my 2010 Jeep Wrangler Unlimited with 'Stock' spare tire. It will not fit. The tongue pin hole will not line up with the hitch pin hole. With it close, access to the wing bolt to unscrew the mast is blocked by the spare tire.
The guys at the Toronto location were extremely helpful as we tried several different hitch mounted racks on my JKUS.
Didn't want to go with an extension so ended up having to get the Sparetime rack.
