No creaks, cracks, moans, groans, or movement as I filled it. I was really quite surprised - I expected it to bend at least a little. Most importantly no leaks! (yet)
The plumbing seems to work as intended. The overflows seem to be doing their job properly. I did a bunch of messing around with the stand pipe, and dinally got it to stop gurgling, and hold the overflow water level where I wanted it.
I started (as you can see) putting the moldings around the front doors of the stand. I also mocked up the molding that will hide the pink foam (no, the duct tape isn't permanent )
I've been watching and learning even though I've not said anything along the way. Both the quality and quantity of your work is amazing, you are truly one motivated DIY'er and my hat is off to you, sir.
