I have an '07 Supra 21V, and I've always wanted to relocate the batteries to gain more storage in the observers seat compartment. One thing I noticed at the boat show this year was that some manufacturers will recess the plastic battery box into the floor to fit under seats. I've been thinking that if I could do that, I could put it underneath the observers seat, right in front of the cooler.
Anybody done this? Is there a way to find the schematics for what is under the floor in that spot?
