Way to think outside of the box and get a lot of additional strength in the truck.
I don't know if I'd go that far. He had to cut and then weld on the frame. Increasing and decreasing the temperature of the surrounding metal to weld on the tubular piece. We don't know how that may have affected the strength of that part of the frame - especially considering it's in an area that is a known crumple zone.
Definitely nice to see some out of the box thinking, but I'm curious as to the longevity and how it performs. Hopefully OP can get us some video soon.
