Quite likely totalled.
This is very similar to, but much worse than, a deer strike I had on a similar 'lite' TT a few years ago. That was about a 150lb deer impacting in almost the same place (front left corner) at 60mph. The front wall was popped out of the corner trim (looked easy to pop back into place, not really bent or broken), the cargo door was demolished and a piece of lower plastic skirting gone.
I was in the process of trading up to the 5er I have now and the dealer said if I brought it back after one last trip in the same shape as he had just inspected, all would be good. After, I expected to take a bit of a hit but he just told me to call my insurance agent because he wouldn't touch it now that the frame was bent. Apparently, 'lite' frames are nearly impossible to repair.
I ended up slightly better off after insurance totalled it than I would have on the trade.
