Does anyone know where to buy a stacked dual battery tray, ideally on that would fit in my 32 fountain fever?

If I cant find ones to stack, I will end up removing the water tank and putting an additional battery there. So, if you know where to find the stock battery tray, that would be appreciated as well.

who needs a water tank anyway. if you fill it with beer the beer goes flat...seriously, I would the farther forward you can mount a batt, the better for weight distribution.
