Trailer build ?

I’m planning on building a 6x12 or 6x14 dual axle trailer for hauling logs and other heavy things, nothing over 10k total trailer weight. Planning on using some 6x2 tube for the outer frame and tongue and 2x2 tube or some c channel for the crossmembers of the frame and was wondering what wall thickness I should use. I’m trynna cut down on the cost and weight but I’m worried .120 would be too thin. I feel that .250 would be overkill for only 10k and would be a lot more expensive. I’ve seen some 14k trailers that are made of 5/16 thick angle but I’m not sure if .120 tube is stronger or weaker. Any thoughts?

There is an engineering toolbox web site that will answer your questions about strengths of different shapes of metals.
