Yes, but what YOU'RE forgetting is that had he NOT made the horrible mistake of allowing someone towing a trailer without trailer brakes to follow him, he would NOT have gotten rear-ended in the first place (and had they both had trailer brakes, the incident would not have been an incident at all). And as was said many, many times, it had a high probability of being MUCH worse.
The DS was poor welding, period. Whether or not it was "temporary", if you're gonna do it, do it right. This is just my opinion, but from the photos, it wasn't a temporary job that failed, it was just a bad weld..
I mean, if something was just "welded on there temporarily to get it off the trailer", why would he have taken the time to grind the weld smooth? I don't polish up temporary/tack welds that I've done for mock-up, nor does ANYONE I've ever met..
This is not bagging on him, he's learning... Just like we used to bag on Taco747 for doing work and CHARGING for it before he should have.. It's just not a good idea to learn on vital parts (like frames, and parts that can easily damage other parts if they break)
