I think the repair is the easier part.
I tried to contact 5 or 6 different welding/fab shops to get it fixed. Only two were willing to call me back. Each had a very different approach to repairing it with one being 5x the cost of the other.
It's at the dealer now, we'll see what they propose for a fix and at what cost.
I don't have any way to evaluate if the existing frame is compromised and if my proposed "bolt on" repair or those proposed by the two shops I contacted are sufficient.

Finding the cause is the hard part. Enough force was added to your frame to bend it. If you make that stronger, the next weekest part will bend/break. My guess is that your cam arms will bend. On mine the frame did not bend, only the bolts tore out. Over time, the cam arm did bend, so after your repair, I'd keep an eye on that.
I understand the next weakest point issue. But the $64,000 question for me is still related to what load the center of the tube frame can reasonably take and how did the force that bent it get applied. JBarca provided one possible answer to how it got applied a couple of pages back.
I'm still working on the assumption that thinner frames combined with heavier tongue weights are not compatible and there's not enough safety built into the design to protect the frame. If I'm right, then the frame is way weaker than the next weakest part and nothing else should break.
If I start bending cam arms, or any other part of the system once the frame is strengthened then I'm going to have to declare the above assumption wrong and figure out what to do next.
