Hey joeortego.... Welcome to the Jayco Owners Forum.
I'm sure you are going to really enjoy your X23B, I know my wife and I sure do!
If you don't know already, one of the main components in our trailer is the refrigerator. And in order for it to work and cool properly, it is important to make sure the trailer is level.
Here is an informative you-tube video on the right way to level the trailer as well as what type of levels to use. Basically you will use a small torpedo level placed on the bottom of the freezer. Once you get level reading, then you can place the curved stick on levels on the trailer. I have mine placed on the front corner (driver side), and another one placed on the adjacent side corner. Hope this helps!
