Hi. We have always been happy with Lippert components and happy with their service, but have not had their slideout covers. We did have several Carefree toppers on our last RV and they served us well. We did have an issue with spring tension for proper retraction, but we are sure that it was issue with the original dealer installation and not with Carefree. The problem was easily fixed and Carefree was helpful. Hope this helps.
