Deleting Spare Tire, what holds up the floor?

[Rev Run D]

I'd like to lose the heavy full sized spare, as I drive mainly within a 5 mile radius. I'm sure someone here has deleted their spare, if you have, what are you using to hold up the trunk floor?

5 Gal. bucket, cut to size, cut the bottom to fit, use tire hold down to hold in place.

Now it holds small items that like to get loose.
