Hyundai Tucson and Kia Sportage both have roll away tonneau covers, and I think they have areas under the boot floor where they can be stowed if you want them outta way altogether
My KIA Carens has the slide away covers however because of the hoist in the back it can’t be used and was just left laying around in the back when I picked the car up.
The cover does have a space for it to be stowed under the floor so I’m told but mine wasn’t and assumed its because of the fixing for the hoist that go below floor level.
For now though the rollaway cover is spending its first three years of life in my attic as I’m sure if its not in the car at the end of the lease I will lose my GCB.
