A couple of things. How warm do you want to keep the trailer? If youare good with 60 at night, you are probably good now - unless we get a cold freeze in AZ - happened once in my 34 years here. I have camped in Big Horns in Wy where ice formed on the mud puddles. I can make it thru until morning with my 2 6V batteries if I am careful and don't run a bunch of lights in the afternoon or evening. The furnace is the killer. I believe they take around 10 amp/hr when running. At 35 degrees or so I think mine ran about 75% of the time - which is 7-8AH. So if you start at 8 pm and run it until 6 am, that is 10 x 8 or 80AH with nothing else running. Since you aren't supposed to run regular batteries below 50%, you need 160AH of battery. I have run mine to almost 0 a few times and they still lasted 5 years at least. Since youhave a genny, all you need is enough to get thru the night and fire it up in the morning.
Good luck.
EDIT: I forgot the 2nd thing. LOL
