I find that if you go on UTube and look at videos of your coach being sold by RV Dealers you can learn a lot about what you may have missed when you "might have" been given a walk through of your coach. For example I think under the exterior TV of the Chateau is the hydraulic pump for the jack system if the attached picture is what you are seeing. Attached is a typical walk around for the Chateau 31W....not sure if the year is the same.
