2015 big horn 3160el owners manual request

looking for 2015 big horn 3160el owners manuals to see the electrical and plumbing layouts along with other info on a used 5th wheel I just bought.
Unrelated question.
How can I get the couch bed to be the same height?
When I open up the couch. The three sections are at different heights with the leather section being taller then the two black sections.

FYI the owners manuals we have had for the last several new fifth wheels from heartland, have been very generic in nature and definitely do not include any schematics for wiring or plumbing in them. Seems as if the new units have them either online now or maybe on a thumb drive.
