Before you go off and buy some tubing with thicker wall, do a bit more
thinking. The max bending is at the receiver. So maybe a six inch
piece of smaller tubing to go inside the tubing that you have and then
weld a foot or so of that tubing that you have under the other tubing.
Since that changes the tubing from 2 inch square to tubing that is 2
inch by 4 inch, it will increase the strength more than going to .250
wall.
Better to just use heavier wall. Also note that with a cantilever beam
the greatest bending stress is right at the point of suspension so
welding another piece underneath won't help.
