I have a friend that has a truck towing outfit in L.Mills, Wis.( Topel's Towing, call them if you need help in the Madison area) and I did a few ride alongs. Incredible job. It wasn't for me, but towing outfits have a lot of experience in those matters. I believe, they would straighten out the unit, and roll it back on it's wheels. One thing for sure, it won't be cheap.
Wow,strong kingpin and fifth wheel to go with it! Seeing this reminds me of those old 70s-80s Volvo commercials where they would intentionally smash their cars to show their durability in an accident. I guess they they could use this to advertise the durability of their heavy trucks.
Years ago that was a regular sight across Wyoming in the winter with CF running from Cheyenne to SLC.
