Curt fifth wheel hitch

I have this hitch which so far I have loved for pulling but the unhitch part has been a pain in the arse the 3 times I have used it there has been no release from my kingpin, which requires me to remove the pins on the upper carrier assembly and raise it above the base so it finally releases as I said a big pain. I thought maybe this is just a break-in period and it will loosen up but after 3 long pulls on a 34 ft rv it still hasn't performed as stated in the instructions, which even state that this hitch will release even under strained conditions well mine doesn't I will still say it is a great hitch I think I just got the Monday or Friday made model... I will contact the dealer I purchased from to find out what my options are...
