I bought some red buckets from Dollar Tree for a buck a piece. To get them to fit, I used a razor knife to make a slit up the side and to trim a little off of the top. Then I overlapped the sides and manipulated it inside the hatch and up and under the black lip of the hatch cover where it sort of locks in. The pictures actually show very I slit the side of the bucket, but you cant tell, even in person. As an added measure, I am gluing the overlap with some superglue. Works great! I bought a larger webbed bucket for the front hatch in the same color red. Not quite as good of a fit, but will do the trick, and also only a buck.
