We had ours weighed four corners, but it was loaded for travel. That's what really counts.
We were pretty well balanced and within weight limits all around. My tools are mostly in a tool bag plus a cheap 130 piece tool set. Plus the usual chairs, a 12 foot collapsible ladder, clothes, food, libations and assorted stuff.
Are you asking where to put the heavy items? If so, you will do well to split the weight between the bays. Remember, water weights about 8.3 pounds/gallon.
Bad decisions make great stories!
