Welcome to the forum. Well the Thor manual I received with my new 2013 ACE was only a generic RV book (perhaps others’ experience is different for their coaches, but I would be surprised) and not really fully applicable to the specific systems and equipment in my coach. It was a nice to have if you have never had an RV before in terms of basic operation descriptions, but that’s about it.
I am attaching a similar commentary from another forum about a similar unit to yours. I think they are basically saying you would be better off to identify all the specific equipment and systems in your trailer and go on line to pull off the manufacturers manuals for them if possible. You might get lucky though and find someone that has more specific information for you already put together. Hope my link works:
