Ya the reason I ask is for fall hunting season... ive already replaced all bulbs to LEDs and will run fridge on propane, and using the furnace to take the chill off... average night time temps would be in the 30s sometimes colder... anyone have an idea on how long the batteries might last with average furnace usage?
Btw trailer is 2000 prowler 20fter
If the converter in your TT is original, it's almost useless for charging, as mine is. Consider replacing it or using the method I described above. Your battery bank at 100% SOC is about 220 amps total, meaning you have about 100 amps of usable power, if you don't go below the magical mark of 50% SOC. The frig still uses 12 volt for the control panel, even on propane. The furnace consumption is entirely dependent upon how often it cycles & run times. The LED's will help but that's only part of the overall picture. My guess is after the first 24 hours of camping, you will need to run the genny with a portable charger for 3-4 hours daily just to get back to 90% SOC.
Take a multimeter with you on the trip & check voltage at the batteries a couple of times daily & you'll get a better idea of things.
This is what I use in place of the hand held meter.
