Its great you did this test because i can say i even got fooled for the idea of their DOM being stronger. But that's because everything i have built i have used USA materials, both USA HREW and USA DOM. And the USA DOM did seem a little stronger but when it came time to put sliders on my dads runner i couldn't build them out of US DOM for what it cost to buy them from Trail-Gear. So i assumed DOM is DOM and after receiving them i realized that is far from true. I think side by side i could tell the difference between USA DOM and Chinese DOM. It was yet again another mistake in buying from your competitor. Luckily the sliders and knuckle studs are the only thing on my dads runner that are from Trail-Mart. And the knuckle studs and backing plate eliminators(which i bought for yours were released) are the only trail mart parts on my pickup.
