TAKPAK is probably correct. Mine is a 2013 16K Reese that does swivel side-to-side but still binds up sometimes. The first thing I do when I am in place is set the first set of chocks. Later, when I am ready to release sometimes I have to just put the truck in reverse to let it move maybe an inch before mine will unhitch. That is the only thing I don't like about the Reese. It seems like if there is any "pull pressure" it won't release and has to be just right. We have hooked/unhooked probably 20 times recently and I'll bet it wouldn't release the first pull on 7 of those occasions.
