Our next modification involved adding large D-ring-style anchor points to the trailer's load deck. These would enable us to use high-grade DOT-approved chains in addition to traditional nylon ratcheting-style straps to secure project vehicles with more confidence. We like this because it also allows us options in case we needed to use multiple anchoring points to secure miscellaneous awkward loads. We purchased these D-rings from a local trailer supply shop for $10 each. Toby Lavender of XXX-Traction in Seaside, California, laid down some beautiful beads, securing one anchor to each corner.
