Installs great with long belt path in the captains chairs. Nice and solid. There is some minor "gapping" at the back/bottom (between the FR85 and vehicle seat) due to the slope of the vehicle seat, but it is not a safety issue if the install is otherwise acceptable. If there is no gap, you've likely got the vehicle seat back too reclined and should re-install.
It installs OK with LATCH in the 3rd row and outboard with long belt path. The install should be checked regularly (as with any seat) in the 3rd row because there is potential for it to loosen over time. And, of course, there's no top tether anchor outboard in the 3rd row, though retrofit is available through Chrysler.
I don't like using lower anchors in this vehicle with the FR85. The long belt path is much more favorable with the seat slope and gives a much more solid (and more upright) install.
My preference would be in a captains chairs, long belt path & top tether. Here's a FR85 acceptably installed in a 2009 Grand Caravan:
