it might work if you turn the front row of rear seats and face them backwards - using the seat as part of the bed and removing the bed extender - or the other way around.. have both seats facing front - remove extender - (you'll have to move or remove the mountings) then slide the rear most seat back to the tailgate and make the bed using the middle row seat and the back seat as the extender - you might have a small gap - or depression to deal with - but nothing a spare jumper couldn't fill - you need to find another horizon to experiment with - those seats are really heavy - I moved my seat onto the front runners and really struggled - i wont be doing that alone again! its a real faff you have to remove the under seat trays first!
