Hey Randy, good question. Yes, the TowSmart # TS85SR is 100% copper wire, not copper-clad aluminum.
That’s a big deal for trailer wiring because copper carries current better, holds up to vibration, and resists corrosion a lot better over time. You’ll get more consistent lighting and less chance of voltage drop, especially on longer runs. It’s also a 14-gauge, 4-conductor setup, so it’s right in line with what most standard trailer light circuits need.
So you’re good there, it’s a solid, reliable option and not one of the cheaper CCA wires that can cause issues down the road.
