I have a R with the official spare, insert and additional floor and think it is great.
It is so well designed, I can have the foldable floor folded up and it gives me some extra space, shopping bag holders and scoops for stuff.
With the hard folding floor flat, it gives a solid higher floor for easy storage and loading.
Additionally with the back seats down and boot floor folded down, it gives a massive solid flat loading/sleeping area.
I'll try and get some pictures if anyone is interested.
