I'm "guessing" the battery is close to 3 yrs old, (same age as tt) and you need a/new battery
in fact two batteries would be better for dry camping


Options, always have options, and the journey goes much smoother

If I get two group 24 batteries, how should I set them up? Do I connect parallel? Would my charger in the trailer handle it?

Wow. Lot's of responses. Thanks all.

More info:

Group 24 deep cycle. 690 MCA. No furnace used. Left bathroom light on. CPE 2000 inverter gen. Fully charged when we left the other campground with full hookups. Will try another battery.

Refrig set on gas.
Have the battery load tested at a auto store. You have the typical NON deep cycle marine battery. Consider 2 deep cycle batteries either 12V aor 6V. Don't run the light all night, instead get one of the portable LED night lights that turns on with motion.

How do you know it was fully charged? By one of the standard and worthless battery monitors installed by the mfg? The primary purpose of these displays is for the sales person to sell the rig... And then did you use power all day and night?

What charger? Many don't do a good job of charging and may also be inadequate with more batteries. Your gen has adequate power.

2 12V batteries are connected in parallel. 2 6V batteries are connected in series. In both cases you will now have 200AH+. You'll need an adequate charger.

Had the radio on from 7 to 9 pm. Should have ran the generator until 8pm. Now I know.

Had just bought the generator a few days ago for this dry camping. It holds a gal of gas. How long would this last? Manual does not say anything about duration.

If you are running the furnace at night then your only actual solution is to add more power (either a stronger battery or additional battery). Dry camping with furnace use is not very practical with a single group 24 battery and even two is marginal.
Good luck / Skip

that generator will run approx 7 hrs or more while "just charging batteries"
using the microwave etc will reduce that by a small amount

To hershey,

Don't ever use one burner on low on the stove to cook a large meal like a stew or corn beef and cabbage using the stove is dangerous. Especially when you are not near the stove in the kitchen or living area, but well away from it, in the bedroom with a window cracked ;-)
