Not sure if you had any replies or not. If the seats do not fold flat, then definitely will not gat a game with the back box folded down in.

Older Range Rover sports up to 2012, the seats fold flat and I carried games around. Range Rover Sports 2013 onwards, the seats do not fold flat, which makes it difficult to slide a cabinet in. No good for games with back box folded. This gave me the ideal reason to get a Land Rover Defender 110. Seats fold flat and the boot floor is plastic and easy to slide a game on. Only slight issue, is that it does not lower down as far as the old Sport, meaning you have to slide out and down to either fix the legs or onto a hydraulic lift.

Older Land Rover Discovery 2 was also a good work horse for moving games. Plenty of access and seats went flat.

Hope this helps.
