    Don't make big piles that you might tend picture for garbage bags. You want support over a big area, but you want easy expansion sideways during compression. That pretty calls for a pattern of separated piles, or strips.

    Now if garbage bags were being used as if the were two sheets of plastic, that would be ok.

    Thoughts on whether or not I should install ledger if using mud?

    I use the ledger board. It helps for leveling too. That goes in level, I mark down from that to see if I will need to shim the apron, and then the mortar if used helps to make the tub feel solid.
    Sometimes if all conditions are perfect, the tub doesn't need anything. Other times, I might use some adhesive on the floor, and finally there are times when the gap is too large for those ways, and mortar is used.
