Thor Hurricane house batts
I have a 2014 27k Thor hurricane.
I have 2 interstate batteries powering the house.
Last night after a week of being plugged in to shore power, I was off grid and the batts died. Nothing was on but the fridge and the heater. Oils T they last longer than a single evening? What can I do to extend my off grid survivability?
Thanks

The heater consumes a lot of power...
Cheapest way is to increase the number of batteries and buy AGM.
Look for VMax Tanks...

I had intended to install a third battery but was worried when these two couldn’t handle one night of warmth.
Is it normal to sap all the battery on one night of heat?

What heater are you using?
Hurricanes come usually with two group 27 batteries...
Those are 100ah at best which means you have a total of 200ah.
If you are using the furnace, that should draw 30A which means you will be drying up your batteries in lest than 7 hours without considering other loads....

I need around 400 amps per night for heat, fridge, and misc. Coffee prior to generator time as well.
Changed to AGM to get that as the FLA would die around 5 AM when they were new

Install a battery monitoring system so you know the actual state of charge of your batteries as well as DC current loads.
Once the system is installed do an extended load test of your batteries to see what their current health is.
This is what I installed in my ACE last year:

Do you have starting or deep cycle interstate batteries?
Deep cycle will run your RV much longer , here's a link to Interstate.

GD,
Are your batteries 6 volt or 12 volt?
100 amp 6 volt in series is still only 100 amps.
100 amp 12 volt in parallel is 200 amp hours.
Furnace uses about 10 - 12 amps an hour.
Here are some examples attached.

I would also say that one night of heat in 45 degree overnight weather is not the same as one night of heat in 25 degree weather.

No!!! Not normal at all. The fan takes very little power to run. May be time to replace your batteries or make sure they are charging during the day when you run the generator or the engine. I put a third battery in my Windsport 29m because I have a 12v fridge that I had JC Refrideration in Indiana upgrade for me and I LOVE IT!!!!! Needed more amp hours and the NAPA RV/Marine batteries, flooded did better than AGM's!!!!!

What?
As already noted it will take more than battery to operate the 12v fan overnight during cold weather on a typical RV propane furnace
Takes about three batteries amps to opmy heating system overnight when below freezing
