So I built a rack with the intention of puttin any tub I want in there...and here are some pics showing different variations. Id have more tubs in there but I dont have any more. Only "issue" is that some require lids.
Heres the list of what it can hold though:
18 6qt
9 15qt
3 34qt
3 41qt
And any combination of those really. Havent tried 28 qts but Im sure theyd fit just as easy.
Top Level 34qt + 2 6qt, Middle 41qt+ 1 6qt, Bottom 3 15qt
