The battery box on my truck was previously relocated under the hood. When it came time to paint the firewall, I moved the battery back under the floor. For me, the box was in the way when accessing the rear of the engine.
Same here. I moved it back to under the floor. Today's batteries don't need maintenance so it's OK under the floor. However, if it was on the firewall it would be easier to get to if you need/give a boost.
