Or in this case an empty space.
A long time ago I pulled out the original holding tank and the platform over it.
I then replaces the center fuel tank and was left with a nice space over it, forward of the ER. What to do? Putting back a holding tank was out of the question as access is difficult. But the space was too good to waste.
The solution is a 1" starboard platform which will hold a 12 gallon water tank (see the reason for this tank in the next post) and a Whale sump pump. The sump pump will take the drain water from the showers and possibly the fridge (if it has a drain).
Forward of this is the afore mentioned battery tray.
