Hey Janet!

The internal dimensions on the # TH34FR98AB are 55.1"Lx20"Wx17.3"H. The numbers on this come out to be a little strange, but that's just based on the shape of the cargo box. This is a great box and system for carrying luggage, camping gear, or road trip accessories without having to struggle to close it. It also includes lights to plug into your vehicle's 4-way lighting connection, so you don't have to worry about it covering your taillights.

If you're needing a cargo box that requires more height, you could go with the GearDeck 17 Enclosed Cargo Carrier for 2" Hitches - Slide Out - 17 cu ft - 300 lbs - Black # H00604 (46-1/2"Lx24"Wx25"T) or if you need more space in all directions, GearSpace 34 Enclosed Cargo Carrier for 2" Hitch - Slide Out - 34 cu ft - 300 lbs - Dark Gray # HGK819 (63"Lx28"Wx40"T) is the way to go. Both of these options include LED taillights since they obscure your vehicle's taillights.

What kind of cargo are you needing the box for? Is this enough space for your cargo?
