I am going to comment on the stitch welds, but not because they're low quality or lazy or anything like that. I'm a bridge engineer, so I tend to have an eye for corrosion-susceptible details. With the stitch weld as it is, water can get in between the joints between the welds which can lead to accelerated pack rust. Going to a continuous weld will keep water out of those areas that trap and likely improve the life of the structure.
