The brahmin feed trough looks the same as a bathtub, but they seem to be distinct items as far as the game is concerned.
I am thinking of doing an experiment at Sanctuary where I store my brahmin feed trough in the workshop and give them a bathtub from one of the empty houses.
Has anyone already tried this?
Can a bathtub be substituted for a feed trough?
(The same question has been asked at gamefaqs but not answered, and I found a reddit thread that mentions a bathtub, but it's not clear if the poster actually built a bathtub or is just being inaccurate and is referring to the feed trough).
