Perhaps you can help me. We bought a new Tiffin and will be getting a toad soon. In the mean time we want to haul two bikes. I like the BlueOx and would like to get the BlueOx car tow set up as well as the BlueOx bike rack. I can't find anybody who can tell me what all pieces I need. I have tried Camping World and PPL RV. It appears I may need an extension as the receiver is a couple of inches back of the end of bumper. Can you give me a breakdown of the parts I need to purchase? Thank you.
