All I have is a 200 liter tank, but I will echo all your complaints (well,
OK I don't need a ceiling mounted winch for mine).

Nice idea in theory, but this fall when it came time to protecting my must
as fermentation was dying down, I just resorted to some heavy plastic
sheeting. I doubt if I'll ever use the lid again.
