Interstate Battery Life

Hi, I have a 2013 extended Interstate. Does anyone know how long I can leave it parked without the battery draining? The refrigerator is running, but we have no shore power. We are also not using the generator. Thanks for your help.

I would say 1-2 days with good sun if you're not running the engine or generator and assuming you don't want to allow your batteries to drop below 50%. That has been my experience.

Install a battery monitor and then you won't have to guess.

He's got one. It's part of the solar controller display.

To prolong battery life, turn off the TV antenna, inverter, propane valve, & circuit breakers (kills the parasitic TV load on standby). Solar panel will help so you just need to keep an eye on the monitor.

If you have like I the 50w it may add a day but you looking to run close the 50%. It also depends on the batterie condition.
Again that is my experience which may different from others.

Depends on the outside temperature, too. On hot days, the fridge has to work harder, so it uses more electricity. If the overnight temps are only in the 50s or so, the batteries will last longer because you won't run them down as far before sunrise. But even then, you'll only get about three days of fridge time.

Basically, without the generator, an Interstate is a pretty bad choice for a boondocking vehicle. No endurance off the grid. That's why it comes with a generator as standard equipment.

I agree - that's why I added 400 watts of solar to my Interstate. I boondocked for 5 days straight at Denali NP in Alaska this summer. Even with some tree canopy and rain every day the batteries stayed charged. Ran the refer, watched videos at night and made 2 cups of coffee with HB K-cup machine (600 watts) every morning and never ran out of power. We used the propane furnace to warm up on cold morning.

Now my boondock limit is water tank capacity. Seems that the gray water tank was biggest limiter. Need to be more conservative with water if I want to boondock longer.

Alcohol-based waterless hand sanitizer is your friend, and good for the whole body. I had to use it that way when I had MRSA and three incisions on my foot that had to be left open untl the infection healed so that I couldn't bathe or shower.

Reserve one of your three soap dispensers for hand sanitizer. You may not feel as clean if you sanitize all over as when you shower, but you will be clean nonetheless. Reserve another dispenser for Go-Jo, for when you get really grimy and need a waterless soap. Leave the third one for a liquid body wash that will also work as shampoo for those occasions when you feel like running water for a shower.

One of the advantages of we older models is that our frig runs on electricity or propane.

I spent 8 nights dry camping last August, running the generator every other day or so to keep batteries topped off, and had not yet used up my small propane tank when I left.

It would seem to me that the propane option would be a good one to mantain on the new Interstates.

Running the generator every other day will work with the new only electric fridge too.
Sounds like the 400w is a good boondocking option as if I boondock with TV and coffee I need to run the generator about an hour in the morning and an hour in the evening to keep the batteries between 80% and 100%.
Yes temperature, sunshine if you have solar as well the batterie condition have a big impact an the time you can let the AI sit without recharging.

You can turn off individual 120vAC circuits by means of the circuit breakers.

To turn off individual appliances without turning off the whole circuit, you can add switches to your outlets. I've done this with my televisions, and have a couple of spares that I use for portable appliances that I don't want to unplug each time.
