One thing to bear in mind is that the center workable part of the table need not be as wide or as long as one’s outer “pontoons” on which the LowRider rides, if your table is designed like this one:
My table is designed this way, and it not only makes it possible to cut wider than the center part by a little bit, but also makes it easy for the Y travel to reach areas off of the center part by a good bit. For a full size table, I recommend this approach, and the method shown by Ryan in the one I linked above.
Another thing to consider is that extra Y reach can mean you can add screw-based clamps to the front of the table, and clamp tall objects to the front of the table, and do CNC cuts on the end of the item that’s sticking up in that usable work area.
