I too have had similar problems. I usually resolve it by raising the tongue and jumping on the hitch and that sometimes works, or moving the truck back and forth a bit as others have noted, but it always has resulted in freeing it all up. I do hear a "clunk" when it releases ... Other times, it works like it is suppose to, so no clue as to why it is problematic and why it is not.
