When connected to "shore power" (such as plugged into any RV park pedestal etc.) the on-board converter (where you find your fuses and circuit breakers) ...converts the 120 volts AC to 12-14 volts DC for your lighting, Television/cigar-lighter, automotive-style AM/FM/Disc-player, etc.... and, if your main Battery Switch is placed in the "use" or "on" position...will charge the on-board batteries.

When travelling/towing.... the 7-way umbilical connecting your trailer to your Tow Vehicle (aka TV) ... will supply 12-14 VDC from the charging system of the TV to the trailer, thereby keeping the on-board batteries charged.

Hi Cobra7: You are new to Airstreams like all of us once were. There are no stupid questions on these Forums. More experienced Airstreamers enjoy helping out a new member. Sometimes the answers are stupid, but the questions aren't.

Seriously, Airstream rather invented the 12v DC systems in modern travel trailers with their "uni volt" scheme back in the early sixties. It was a "converter", or transformer that converts 115vAC to 12v DC. Then Airstream made all the lights, water pump, furnace fan, and vent fans run on 12v DC so you could have all the comforts of home while on a caravan in Africa. It was a good idea.

Since the converter is making 12vDC, why not spend some of it charging the batteries for the next night where you may not have "shore power" to connect to. Modern converters have circuitry inside that properly maintains the batteries and doesn't overcharge them.

Just a reminder, you can not run your air conditioner on household current of 15 to 20 amps. You need about 3000 watts, or 30 amps to start and run the AC. Low current can damage the AC motor.

Welcome!
Advice from the first two posts are spot on.
Keep in mind to monitor the battery level as draining too far down and leaving it can damage the batteries.
Get a good trickle charger for storage.
A good “suitcase” solar panel can also charge the batteries when no A/C power source is available.

Thanks y’all for the quick responses. I pick my new 25FB up on Wednesday and I have a lot to learn. Hopefully the dealer will go over everything slowly with me.

Make sure they go over everything. Slowly. Repeatedly. Video the whole thing so you can watch it later. There’s several delivery-day tips if you search the forum for them. Since you’re new, use the blue search box from the desktop/web version of the site for best results. Plan on spending 2+ hours on a predelivery walkthrough. If you can, spend the night in your trailer on their lot, and ask follow-up questions in the morning. You’ll also find those silly little things that need dealer repairs before you’ve gone anywhere. Most importantly, have fun!! And keep asking questions.

Most (maybe all, I don't know) Airstreams only charge the batteries from shore power when the use/store switch is in the use position. I'm sure this, along with 6,000 other things, was explained to me by the dealer when I bought my Airstream. But if you ever wake up in the morning after being plugged in all night and your battery monitor still shows “low,” this could be the reason.

Recently I read a comment that made an important point about what you need to accomplish in your pickup walk through. You need to do a complete inspection for flaws and damage. Infant mortality failures and manufacturing errors are covered by warranty. Physical damage that you don't identify at pick up most likely will fall to your pocket book coverage. So look it over while you listen close and take notes. It's a lot to cover, so bring your "A" game. Pat

There are no stupid questions. As stated by others, make sure your walkthru includes a check of every system. Put down all four stabilizer jacks, test every light switch, and turn on all faucets, hot and cold, etc. Take your time and ask every question you can think of.
