What do you guys think about this guys unistrut/super strut under mount bolt vs center bolt setup. In later videos he tightens down the under bolts. I like that you could collect rain with no gaps in our desert, but it seems weaker. Each panel would have 4 bolts through the back aluminum housing strip only vs the larger gap with the center bolts and a square washer holding down the panels. I wonder how strong 1/16" aluminum is to tear through to fly away with the under/rear bolt.
I read the aluminum unistrut rails have 350 lb uplift strength with the nuts that are spring or slide in, like this guy has that utilize the lip. I assumed a full center bolt through the chanel with washers on both sides would be better, is that overkill. Would you rear/under bolt them like this guy?
I assume stainless bolts with locking washers would be better vs steel that could rust. Either way you have dissimilar metals.
