A 5th.wheel that drops on a truck usually hits the truck box walls and has some leading edge damage,it shows none.What did it hit coming down and how far did it drop?I doubt that the hitch hit the bottom of the truck box and not touch the top of the truck box.Do some measuring on a similar truck box and hitch height.You should be able to look up into that area of the 5 th.wheel around the hitch with a bit of trying.Aluminum takes a fair bit of bending and wants to return to its original shape.What is holding it from doimh that,bent or cracked hitch attachment and supporting frame??Check every seam and joint inside the front bedroom for any movement or cracking,loose screws etc.It didn't have a goose neck attachment did it?
