2013 model 330MKS-Will be two years in late July. Over 10,000 miles with no issue BUT there is a know issue with wear/tearing on the bottom of the slides with Darco wrap where the rollers contact.. With the Darco, there may be an issue will water seeping through the edge of the Darco if not watched carefully. Members on the Primetime forum has been asking for months about repairs, modification or what Primetime is going to do about it but Primetime has remained silent. One of the Mods., RV Guy used to be active but since the questions started he has disappeared. I believe the Crusader offers a lot for the money and quality is good as any unit in that price range.
Lot's of frustration. Go to the Primetime forum and search for a post by Platokidd under this topic "Slide out /underside wearing "
Many posters comment about the good factory service but there are 24 pages of comments and Primetime has been silent.
