FWIW. (and, not seeing the entire damage, rear of truck, etc....)
If you still want to use the hitch take it to a frame shop and see if they can pull it out and then weld in a plate for strength.
If you don't need the hitch, remove it and run it as is. Either way it's not the end of the truck. Cheers
If the bend is behind all the suspension mounts all that is compromized is the hitch and the ability to tow.
I'd definitely not tow with it. Remove the hitch and carry on.
I'd go to an Auto Body capable of repairing the frame but I'm a bit anal that way.
This seems to be a phenomenon with new trucks..... growing up with farm pickups from the 1960s I only saw bent frames after a high speed excursion into the ditch and going airborne off an approach. Guys today bend frames towing trailers on "roads".
Curious, what year of Land Cruiser needs a new frame?
