i have two of those indoors. when we cut, split and stack, the 12x24 lean to is stacked to the ceiling and completely stuffed to the brim mostly with harvested wood (we live near a swamp) so swamp maple and swamp willow
Just for what it’s worth, I had put a bunch of smaller stuff on a rack then piled bigger stuff on top(and yes, I knew better). We ended up getting an epic rain that night and it added just enough weight. The results can be seen below :). By the way, that’s in pitch darkness, 100% infrared.
