Op here. For now, false alarm. The mobile tech was here. Extended and retracted the slide. No thunk. He was under and watched the rail. I am relieved, but I know that sound was distinctively different from the usual. I will have the newMar service center give it a good look when I'm there for my annual service. Thanks for everyone's input.
Did he check the motor mount bolts? To tighten you must NOT have the room fully extended or retracted. That relieves the pressure on the motor mount. For his service call, he should have checked them. Doug
