Time to shop dealers.
It can be difficult to find what you want "on the lot" as dealers order what in their opinion sells best -- it's their business model. Been 6 years now since I bought this Expedition and I had a difficult time and long search to get one with the "bench" 2d row seat. Not only does this allow 3 passengers back there but when the set cover in in place my Dachshunds don't keep falling on the floor in the big gap. This cover hooks between all 4 headrests so they are pretty secure.
My daughter's Brand X quasi-SUV has the "captains" chairs in the second row which are very convenient for strapping in her two pre-school children in their car seats (or so she says
. )
