Would this size allow one bike rack to fit to the side on a 2013 Subaru Outback?
The Skybox 12 is 92" long x 24" wide x 16" tall. If you have factory cross bars, it needs at least 24". If it's too tight a fit, or you don't have factory cross bars, you can always add some rail towers and add Yakima cross bars that are much wider.
