My experience with trucks like we build for prelanding and caping NOT just to go full kill, is to put storage behind the axle. My Tacoma I had lots of weight that didn't change behind the axle, fluids, tools, jack, spare, spare parts etc was easily 400lbs. Cell behind axle changes weight as it is used. We aren't using the trucks to the extremes where shocks get so hot valving fades a noticable amount that the lighter rear weight benefits. Now I'm building my Ford with cell behind axle because it's just a go fast toy not my camping prelander rig.
