I'm wondering if anyone has had experience in installing the third rear facing seat in a wagon. I've been told that this can be done with relative ease, and that the result will be just as if the seat had come installed from the factory. If this is true (and if we can find a seat - anyone willing to part with theirs?) it would simplify our search for a wagon, or at least open up a few more options. Just wondering if any of you have done this, or seen it done. I'd like to know how the end results look.
