I wasn't far from your place when it turned loose, just got back to my place. Deafening inside the truck it was coming down so hard.
BTW, I did the same to my trailer a couple of years ago. The loaded plates are definitely the way to go, and almost the same money-wise. Even though I'd shoot some grease in every once in a while, it had been a few years since I'd stripped them down and cleaned and repacked. One spindle was just shy of being scarred....cleaned it up with some emery cloth, but not many more miles and I would have ruint it. Have a couple thousand miles on it since the rebuild, and it's held up fine.
