Keep in mind that the DC lights in your trailer will drain for around 1AMP DC current for each bulb burning. First thing is charge all of these out for LED lights or at a minimum change one to use for LED when you are camping off the battery.
The fridge will probably require around 5-6AMPS DC current...
If you had to use your furnace blower motor it draws around 6-8 AMPs DC current.
All of the other parasitic drains (sensors-etc) will draw about 1-2 amps all the time.
Need to take an audit of what you want to run off the batteries when camping off the power grid and beef up your battery accordingly.
You should pick up a DC VOLTMETER (Multimeter) from LOWES-WALMART any number of auto parts stores $7-$25 each. Never let your batteries drop below 12VDC which is around 50% charge state and recharge right away back up to at least 90% charge state as this will shorten the life of your batteries big time.
Alot of folks like to INSTALL a PSW INVERTER to run their home entertainment items.
I would want to have around no less than 200AHs battery capacity when camping off the power grid...
Make sure you on-board converter is a smart mode charger type nad use a small 2KW Honda type generator to run every morning to keep your two batteries charged back up to their 90% charge state. Then they will last for the next day/night off the battery.
Just can't show up in the woods and have it all work. Takes some planning...
Most folks like to have two batteries when camping off the power grid.

Thanks for the response Roy! I have a DC voltmeter, and never have I even been able to get my battery to go above 12V....I'm confused why you say I shouldn't let the battery drop below that......
