I had a similar problem except the right side was moving faster than the left side causing a stoppage. I called Lippert Customer Service, they diagnosed the likely cause. Solution was to adjust the slide which I did following the instructions in the Lippert manual, which has good info on the procedure, carefully marking all adjustment points at the start. Hopefully that is all that is required in your situation. Recommend you talk with Lippert Customer Service. Have had great luck with them. They knew what was wrong and talked me thru the necessary adjustments. Took me an hour being extremely careful, a competent tech probably could have done it in 10 minutes. Since you have a 2018 and new, if you are close to your dealer maybe they will address for you under warranty. I have read many dealers will not do slide adjustments under warranty once you have put usage on the fiver, citing owner maintenance responsibility.
