What size buckets? I have one now, but not as Keezer but as actual freezer since the other one broke down. I have the 7.9 gallon bucket and I doubt two would be able to fit on the floor, one could fit on floor and one of hump.
But I do not have the 6.5 size bucket so I could not tell you if they would fit if that is what you have.
