Mine has held together very well and it's 10+ years old. I did break a spring but it was a cheap $40 repair. I bolted mine together so it doesn't fold. Tows great and I have added a few extras.
Get the wheels balanced. Trust me on this.
I bolted a waterproof tool box and spare to the tongue. A jack too.

Installed stainless eye hooks all around. Use red locktite on these if you choose to add.
