How do you secure your motorcycles inside your toyhauler?

I also need some flexibility. I go from hauling just the Harley, to the Harley and the KTM dirt bike, to 2 full size ATV's or one of each. The Harley always goes in the fixed Condor chock, the KTM uses a moveable chock like above, the ATV's use moveable D rings in E-Track mounted along the sides of my garage floor.
