Tim, I think if I was you I'd go look at a few, load the kiddos up and see what you're dealing with. I'm a big kid at 6'4" and my seat is always all the way back, my boys have plenty of room in the back but aren't in any kind of booster/car seat.
I'm a fan of Jeeps and would recommend them to most people, I just wonder if 3 seats across the back will fit well.
