We have a 2014 Winnebago Vista which came equipped with Lippert leveling system. A year or so after it's purchase (new) we started having a problem with the system either not retracting or extending. Several visits to RV repair shops (Tucson to Spokane) ensued but repairs turned out to be temporary (1 week to 3 months). We finally bit the proverbial bullet and went to HWH plant in Iowa and had the entire system replaced. It has worked unfailingly ever since!!! Before the replacement, our frequent communications with Winnebago and Lippert brought no relief. We have not communicated with either ever since though we still own and travel in the 2014 Vista.
