I can't imagine that it (Cocorro) wouldn't go in tightly in the plus one of a 2011 or newer Ody. I managed to get mine in my 2009 Ody. It wasn't easy. Took lots of tries. Had to change out the pool noodle I was trying to use and install a few different times, but I got it in. It's still reasonably tight over 2 weeks later, even after a long road trip. I like the install to be a bit tighter than it is, but it doesn't move more than 1/2 inch or so. I used the Euro routing and I top tethered after I got it in tightly.
All that said, I have a total love/hate relationship with the Cocorro. It's the seat I want to love, but absolutely hate installing. And I can do really well with installs. Never had as much trouble as with this seat...I felt similarly about installing the Cosco AOE's rear facing. I love that seat, but rear facing installs stunk in lots of vehicles. When the Cocorro installs well, it really installs well. When it doesn't, it's a PITA. LOL
