I bought a Bike Rack from Costco that can carry 4 bikes at a time. The problem is, the spare tire on the back of my Jeep will not allow the 2 inch receiver to go all the way in to put in the pin. My question is....can your hear the drum roll...The 2 inch receiver fits in there enough that I could drill another hole and this would leave me approx 2 inches from the end to the new hole. Has anyone done this?...I could buy a 8 inch extension but now we have the issue of it being too long. Any suggestion?
