We recently purchased a 2025 Lineage after seeing it at both the Cleveland and Columbus Ohio Recreational Vehicle show. There we met two different sales representatives from Grand Design, both of who talked very highly of the roof design and how it was so much better than than the traditional roof with seams and caulking and how this was much better at preventing any type of roof leak. We took our Lineage on its maiden voyage two weeks ago and much to our dismay and disappointment we had several roof leaks. Upon returning to Ohio and taking the Lineage to the dealership for repairs now we are told that the Lineage must be returned to the factory for repairs. The repair is scheduled out an entire month from now and it was estimated to be in the shop for two weeks, but they could not confirm that for sure. I would think that since Grand Design is trying to move into the motorized motorhome section, prioritizing repair of these issues would be their number one priority but apparently that is not the case.
