Center of Gravity is adjustable on every unit, adjustable by how you load your 'stuff'. By that, I mean the heavier items not clothes or books...
Heavier stuff forward moves the Cg forward and full tanks move it rearward. My FW, batteries and utilities are all forward and I carry my tools and items like chainsaw and winch on the floor of the truck in the backseat which moves the 'adjustable Cg forward as well.
I'm nowhere near or at my maximum axle loading so while it makes no difference for me, it 'may' help with handling. Never noticed any issues however. My truck always rides like a lumberwagon. Just part of it's 'charm' I guess.
