I am going to be getting a tray type bike rack for the rear of my 07 CR-V. I am wondering if anyone knows which brand of 2" receiver has the most clearance. So far, it appears as if the curt 13555 has the most, 16" measure from the top of the receiver to the ground. The hidden hitch is an inch lower at 15". Are there any other brands to consider that might sit higher? I am getting a kuat NV http://kuatracks.com/products/bike/the-nv/ and the base sticks out a little bit. Thanks.
