Bill Pumphre built a Scooter Holder for transporting a three-wheeled scooter in his pickup. It is simply a triangle-shaped steel wedge that hooks into the truck bed. The scooter's front wheel rests in the wedge when the truck's tailgate is up and pushing against the back of the scooter. The wedge can be easily unhooked when the bed of the truck is needed to haul other cargo items.
