What is the equivalent replacement for a 6 x 8.2 mild steel channel in rectangular tubing?

I am wanting to design a trailer frame using rectangular tubing with the same structural strength as 6 x 8.2 C-Channel. Using 2 x 6 rectangular tubing, what is the thinnest I can go? I am not proficient enough yet in Inventor to simulate it on my own and I am not a degreed engineer. Any help would be greatly appreciated.
