I had a BX40, much weaker than the HDBX series, with a TH3 on it. No problems.
A friend has an HBX56 with KLM34XA, also no problems.

The only BX type tower I have known to fall was a guyed one. But it was
rediculously overloaded, and extended to 80 or 90 feet with straight
sections that Rohn used to sell.

I have not personally seen missing rivets on these towers.

Get an old pair of workshoes. The sides of the shoes will quickly become
torn. You won't have has much a problem as I had on my BX since your
sections are much bigger.
