Hi Leslie,
What specific dimensions are you needing on the TorkLift SuperHitch Magnum Trailer Hitch Receiver # TL74FR? This hitch is designed for select GMC Sierra's and Chevy Silverado's. You have your vehicle listed as a 2019 Volvo XC90, if you're needing a hitch for this vehicle then I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # 76194. view full answer...
The Thule Vector M Rooftop Cargo Box # TH613201 has interior dimensions of 73-1/8" long by 25" wide and 11-9/16" tall. You are going to want to compare these dimensions with that of your suitcase as not all manufacturers use the same measurements and I know some will have an expandable design which may also affect your decision. view full answer...
