Last weekend we went camping and we couldn't get the truck unhooked from the trailer. When I tried to pull the lever on the Pullrite hitch to disengage the King Pin the lever would not budge. I raised the trailer up and while doing so pulled on the lever at regular intervals. Next I lowered the trailer back down and pulled on the lever at regular intervals. I did this for about half an hour since I couldn't think of anything else to do. Finally, and for no apparent reason, the lever pulled out like it usually does and the trailer was free from the hitch. This hasn't happened before.
Any ideas on why the lever wouldn't budge?
