Mine has been holding up well. Its massive. I think its just a little shy of 100qt, but im cool with that anyways.
I have put one fitting in it, I used the dimple and silver solder method. When I pulled the fitting through, the wall split in several places so it required quite a bit of solder. I havent put another fitting in it for fear of the metal splitting irreparably, but who knows.
The manufacturer should have put a ripple near the top to help it keep its shape, it kind of goes out of round (the lid takes some finessing to get on).
Its cheap, its massive, its flimsy.
Texas is awesome.
