**Clarifying my message above**. Brakes locked on Thursday, didn't know pin was out till Friday AM. Put it back in place and RV brake seemed to relax. TV battery was dead, had to jump it. Then disconnected RV battery cable. Saturday, hooked to shore power, disconnected TV to RV power, pulled RV a foot to insure that brake was not on. Now trying to disconnect RV from truck and pin is tightly stuck in the hitch. Service tech put it in at dealership so we never have pulled it and have no idea of how "tightly" it might fit into the device. But it had popped out as we made tight backup turns so seems that it pops our easily.
