One option might be to fit drawers in the rear and ensure they are high enough to fit a battery under the top shelf. I plan to do this with the Off Road Systems drawers I have just fitted to our 110. However, 220 for the battery you have is taller than the standard drawer height so you would have to ensure your drawers were specially designed, or else get a lower battery.
Another option might be to fit a battery box behind the rear passenger's wheel where some people fit water tanks.
A third option would be to put the battery in a battery box such as an Ark box, strap it down and connect it. That way the battery box can be removed when not needed.
