Is this taxi allowed on the airfield and onto the parking areas? If so do you have their contact info? The idea is to be able to Sherpa an RV-10’s worth of cargo in one go without transloading at a gate.
It goes right to the plane and can go off-field into town. It's a volunteer run operation. They can be reached by phone or you can inquire at places like Vintage Flight Line operations who has a radio link to them.
