I have read that the hidden hitch one sticks a bit farther out than most. It will allow for some bike racks to fit without an extender (that wouldn't otherwise). It's my understanding though that it can also bang your shins because of the longer length. Other hitches that are shorter (more like the factory one) can use a hitch extender for about $20 at Harbor Freight with coupons that are all over the place. http://www.harborfreight.com/12-inch...der-98677.html
. You can get a pretty good deal on a shorter length one here.

Good luck finding a good solution.
