1st time 5th wheel owner sliding bar hitch question

You might be able to replace the head and keep the rest of the hitch. My 4 way tilt head is held in place with two pins and could be switched out. The pins also make the removal of the hitch easier. The pieces are easier to handle individually.

Call the hitch company, if they are still in business, and ask them if they have a tilting head for the hitch.
