5. There are several things wrong in this photo. First, the frame notch wasn't properly gusseted after it was cut out. Second, there's poor penetration in the "welds" along the areas connecting the square tubing to the original frame. Lastly, the tubing used to create the step notch is only half as tall as the original rails and only extends about an inch past the area that was cut out. This means there's a huge stress point above the notch, which means the frame will likely crack in this location.
