Our family of 7 has really enjoyed this RV. We have owned it since January 2019. It has had regular engine and generator maintenance. The tires and water heater were replaced in 2019. We replaced the carpet flooring with hardwood flooring. The sofa, dining, and captain seats leather upholstery was replaced in 2019. The two slide awnings and two main AC units were just replaced this summer.
FYI:  The photos in the ad are of our RV, taken by us.  However, the video link is to a useful quick walkthrough of a NEW unit by a dealer taken >6 years ago.  Obviously our RV is not new and does not look new.
