Friends of ours have the Shadow Cruiser version of this floor plan and after 9 months have had no issues. We have a different Shadow Cruiser and have had issues but noting major.
Iโd suggest checking the factory caulk job on the roof. I found ours to be lacking around the shower skylight. The second thing is check the wheel bearings sooner than later. I didnt dig into mine until the 2 year old mark(approx 3k miles towed) and found the factory grease job to be lacking and a couple of bearings were starting to show moderate to severe wear.The preload was also nonexistent.
