Furnace while boondocking.
For a 33' travel trailer, how much battery usage can I expect from the furnace? They are calling for low 40s over night and the women like it warm. The only site left was no electric so I booked it....

50 aint guna work with my wife. More like 65 is what we like. You are starting out with minimal battery. There is nothing wrong with dual purpose 12 volt batteries but they arent GC2 or true deep cycle 12 volt. You have to start out in top shape. You basically have enough power in two 12's if they are in good shape and the specific gravity is UP. Have you ever checked the gravity? You can charge for X time and see high voltages but you may not be actually charged all the way.
The specific gravity will tell you what is really going on with the battery and show diffwerences in cell gravity. You also need to look at your charging system. If it's only doing 13.6 at the converter it may only have 13.5 or 13.4 at the batteries. Ann upgraded converter will get 14.4 v or even up to 14.8. Having a meanwell power supply is also handy for equalizing. Your battery bank is your cash in the bank, your energy use is withdrawals and your charging capability is your income. You also have to pay the banker for battery resistance and system losses.
