Agreed it has been an issue since 2008.

Yet, the "cheap design" of plastic end tanks crimped to aluminum radiator cores was in the Super Duty for a decade prior to 2008, going back to calendar year 1998, when the 99 up Super Duty first hit the streets that spring.

For 10 years, between 1998 and 2007, that design worked without the rash of reported radiator leaks that has plagued many 2008 and up Super Duties. That the plastic tank to aluminum core radiator design worked for the 10 years prior, and then suddenly didn't work for the 10 years since, is a strong indication to look for what actually changed in 2008, if it wasn't the plastic to aluminum design. The engine changed in 2008. But the engine changed again in 2011 and the problem that appeared in 2008 didn't go away. It prevailed with the new 6.7, and with the updates to the 6.7 in 2013 and 2015. M-chan68 just repaired the same issue on a 2016, as mentioned upthread.

So what changed in 2008, that is different from 1998, and that is the same as 2016?

The front frame design.

Agree 100%, and additionally, the Mishimoto with fully welded aluminum tanks are also failing at a similar rate to the "cheap" factory rads with crimped on tanks (and in the same place), so it kinda rules that out too.

Wow that sounds like a factory defect. Are the '17s easier to work on?

Well, being that it was a gasser, there was substantially more room under the hood. This was the first time I've had to replace a radiator on a gas truck. A better comparison would have been if it were a diesel. But, all in all it was relatively painless I guess you could say.
