Is that a hitch extension to provide clearance for the bike rack to clear the swing away rear tire carrier? I'm just scratching the surface of looking at bike racks for my rig. I have the original bumper on my 2003 Ford e350 with aluminess spare tire rack.
I have the Platform style rack that holds 2 bikes. I didn't really need the extension to clear the rack, but I wanted a little more height when installing the bike rack.
