Here is your Brochure
for your coach and as ELF11 said turn on your furnace put water in your fresh water tank and enjoy your trip to where ever.
Your coach is heated in the lower tank bays as brochure says and as my coach has and we have traveled in 1* temps many times and camped in same temps.
If I find anything else for you I will post here.
Here is a video
about your coach and about the 9:20 mark the salesman goes through the utilities of coach before going inside.
You say you have a Ford chassis but the video will point out the coach function's not just the chassis function's.
If you have the Norcold 4 door fridge you will want to look at this link
because there is a recall on that fridge if dealer didn't happen to mention it to you..
Couldn't find a owners manual on coach but I am sure people in Thor Forum
will help out with questions.
Good luck with you coach and safe travels.
