For your 2018 Subaru Outback, the Thule Motion XT Rooftop Cargo Box - 22 cu ft - Black Glossy # TH629906 may work, but you will need to take some measurements to confirm. The crossbars need to be between 23-5/8 inches and 36-7/8 inches on center. There is also a measurement for the hatch to open without interference which is at least 55 inches from the front crossbar to the line where the hatch meet the roof.

The Thule Motion XT Rooftop Cargo Box - 18 cu ft - Black Glossy # TH629806 requires that hatch measurement to be at least 51-1/4 inches with the same crossbar spread. For comparison, the Force XT # TH6358B measurement required is 51-1/8 inches.
