I have a '17 SLT1 configured 2-3-2. Like you, I could not find a 2-3-2 anywhere in the southwest, so I ordered one. It took about 5 weeks, and there was no price difference. The bench is 60/40 and either or both sections can be folded forward to provide access to the 3rd row with a simple pull on a lever in the seat back. The bench also will slide forward to provide a little extra foot room in the 3rd row.I've been casually looking up and down the East Coast - and NOT for this seating arrangement per-se, but certain trim levels, and I've yet to come across a 2-3-2 seating arrangement (although it supposedly exists). Every single one of them (in the trim levels I've been looking at) is 2-2-2 (2 Captains Chairs in the middle vs. a bench seat).
I disagree with the folks who complain about difficulty of access to the 3rd row.. Granted I only use ours 2 or 3 times a year when my I need to haul more than 4 kids. They have no problem at all manipulating the seats and getting in. I wouldn't recommend it if you are hauling old folks though. I don't think crawling in from the door is any more difficult than squeezing between the two captains chairs.
Bottom line, if you need to seat 7 it does not matter how difficult it may or may not be.
