Or give me ideas of how you do it.
I don't want the bikes to be taken apart as that sort of negates the idea of having a van....
Do you know if you you can just buy the clamps for those racks? As an alternative I'm thinking of installing a wheel grip on the bulkhead & a clamp on a hinge on the floor that will come up from the floor in the same style as a roof mounted carrier.
Any other ideas welcome!
