i did them both at the same time so i really can't say. if i have time in the near future i'm looking into doing a fuel cell underneath the bed in the middle, the battery in the bed on the right side, and the nitrous bottle in the bed on the left side. (both towards the rear)
well something worked for ya! hopefully it works for me lol.
