I think foam is necessary because there are no stingers to mount the tank. I made a fiberglass channel that runs water down the side of the tank to the back. Did not foam the back of the tank and left a void. Installed a drain tube to the back compartment that I can drain any water in there. Also moved up the tank a few inches so I can reach down and replace that drain tube when the time comes.
