I have a 1999 dodge grand caravan I got 3 across my back seat today in what I thought would have been impossible. I got a FP booster, Regent, FP booster. It is tight to buckle the boosters but the kids that will be riding in them can buckle them and that is what matters. So It makes me sure that I can do a Frontier or a Nautilus in there as well in stead of the regent, as there really is no puzzeling of these seats, it is just straight across, so my 99 GC is bigger than my friends 01 T&C as she can barely do a Natilus and 2 FP boosters.
