That's why we only made it 6 tubs tall. If we need more rack space in future, we'll just build another one. 6 tubs is big enough!
I think we'll just rent a dolly. That will make this absolute cake. Even I can pull one of those, so two of us should be able to get it done. I don't know the exact mechanics of how the dollys work but boy do they help take the load off! Even with stairs.
It's only like 7$ to rent one, and we'd only need it for, what, 30 minutes tops? I'm sure they'd let us rent it. But I'll call to be sure.
Thanks for the advice! I'm so stoked for this rack! We've put painstaking work into it thus far and only the bottom parts of it are done!
