Mega-trouble unhitching

Over the past few years we have Great difficulty unhitching TT. Used to be I'd stand on truck back bumper and jump up and down and hitch would release and truck ball would drop out. I almost dread arriving at any campsite as this whole process can take 30-45 minutes and yesterday set a record: 1 hr to release TT from the ball. Great angst and confusion: what are we doing wrong? We have have been TT'ing for a long time and thought we knew what we're doing.

I have inspected TT receiver socket. It is fine. Looks nothing like the guy on recent TT blog who posted horrific photos of his set up.

Also last September I talked to mechanic in a Reno TT shop about all this and I gained no insights from him.

Would appreciate helpful input from other TT'ers who have experienced this and figured it out. We are currently camped on the Columbia and the way it all happened last night when we arrived I am concerned now about even getting this TT hooked up so we can go home on Saturday.

It is incredibly easy and quick to disconnect a TT hitch. Your dealer should have walked you through this process as part of the PDI you paid for. When in camp chock the trailer wheels and release the hitch lever, then rock the truck/tow vehicle back and forth a half inch until you hear it release and/or feel it. Should not take more than 15 seconds if that. What you are doing is releasing the 'bind' in the hitch. Whoops, just noticed others posted this.
