My single experience with that repair went as follows:
Repaired one side as you did.
Repaired the other side by cutting out a maybe 3" square at that weak point.
Thicker gauge plate. Shaped it using a vice and 3/8" rod. After welding it up I blended it out with flap disks to the original gauge. It isn't noticeable (see pic) and so far defeats that weak point.
It's been knocked over a few times since then on both sides.
My wife backed into it 1x.
Homeless guys-related knockovers 2x.
I "may" have put it on the side stand out of balance 1x.
