I lubed it up, wiggled it around - twice - second time, it came loose and out. So that problem is solved. Now I have to lower the spare tire to get to that disconnect. Everyone once in a while, or maybe more often, truck manufactured come up with what I call a bone-head improvement - this is one. Nearly impossible to get to the disconnect to remove the tailgate. One answer here was to buy an extension, which I tried, but so far - only fits up to 2019 Chevy. So will keep searching or have one made if that's possible. Truck campers need tailgate off and on more than other types RV, so it becomes a PITA to do it the way it's set up now. I'll find a fix somehow. But my camper is on the truck more than off, so that helps.
