We went to move our slide just behind the drivers seat on our 2018 Newmar New Aire 3343 and we heard a very loud pop sound. We stopped immediately and inspected everything then proceeded to hit the retract button once then the extract button. We only moved a little at a time initially, but then went ahead and moved it all the way out. Fortunately, we never saw any parts sitting anywhere and the unit still worked. It moved back in later that day with no issues. We were just concerned something might have broke or failed inside the mechanism area and behind the walls or floor that we just can't see, but maybe you all are aware of a similar event.
Thanks for any comments regarding this issue.
