Having the rack sit up on the SwingBase while a GearLocker rides underneath is such a smart setup for camping trips. Both bikes stay rock solid on washboard roads, no wobble at all.

Loading two bikes on the DoubleUp takes maybe a minute now, and the design means I can still drop a GearLocker underneath without pulling anything off. Solid hold on rough pavement, no wobble at highway speed.

Bolted this onto the SwingBase and it clears the GearLocker underneath without any fuss, which was the whole reason I went this route. Loading two bikes takes seconds and the trays don't wobble at highway speed.
