I would think that the 2" box tube would most definately be weaker if 50% of its structure was cut out to make way for a jack that its not welded to. I am going to have a plate welded to the bottom side to add the strenght back. I spoke with my neighbor (in the concrete business with multiple bobcats / excavators/ trailers), and they way he put it to me made sense. he said that if you take a 4x4 piece of wood, and at the end of that piece of wood you cut out a 2" x 2" notch, then place weight on that very end it will break much easier because 50% 0f the structure has been taken away and then required to support the entire payload on that end. My understanding is that "box tubing" is boxed for extra strenght.....otherwise it would just be made with "L" shaped strips of metal instead of stronger box tubing. Anyway....maybe I need more education on this subject. :confused3:
