The 10 gallon tank I bought for less than $40.00 has all of the outlets on the one end and it works for may installation.
Of course my installation is nothing like the original. I have it mounted in the rear compartment on the left side with the fill moved from the right to the left.
I moved it since I have all of the utilities on the left, water tank, pump, fill hose reel, battery
, and charger/converter.
The difference is that the vent that comes out at the top behind the water reel. The new one has the vent on the other side and works better for me since I have since installed a separator between the tank and reel so that when the access door is open this seals off the reel and battery
box to confine any critters to this area.
Perhaps this helps someone.
