Seems like a strong battery to me. The mattresses say 120V only so I guess I can't run the mattresses w/o a generator or shore power - but that's a little odd b/c I plug the mattresses into my outlets on the camper. But I suppose my battery doesn't actually run these outlets I guessing.
Our next trip is at 8500 ft. elev. with no shore power, so I'm wondering how long I can expect this battery to power occasional ceiling dome lights - probably use for a few hours each night AND my heater occasionally at night (since I can't use the heated mattresses)?
I'm thinking my built-in heater draws a lot of power. I can fire up the fridge on propane once we get settled or just use a cooler. Can I make it 3 nights with occasional heater use at night and interior lighting? If not, I guess it's essentially tent camping which ain't so bad I suppose! lol! Thanks!
first, you need to learn how the electrical systems work in your popup.
there are two separate sides, 12vDC and 110vAC.
your outlets ONLY work on shore power or with a generator. therefore plugging your heated mattresses into the outlets won't work if you only have your 12v battery power.
i suggest you Google, the 12 Volt Side of Life. this is a good place to learn how the systems work.
second, yes your FURNACE will use up more battery power than anything else in the trailer. it's a power hog.
your fridge will draw very little battery power to operate on propane.
as far as how long the battery will last, if you use the furnace all night, it quite possibly could be drained by the next morning.
