Hmmmmf! I think they need a skin in the tank cos their welds aren't leakproof. My calculations give 23.75 gallons going by Daves dimensions. Dans and Daves tanks are different in that Daves has a cutaway front edge to access some of the rear end hardware presumably. Dans has a separate lid we see wrapping the edge and I assume Daves has a panel on top to install the bladder. The one I'm making off Daves dimensions is almost done. I'll post some pics shortly.
