Yep, I have an appt with my favorite RV place in Houston, and they say that if I notify airstream first I could get reimbursed. The local dealer isn't someone I want to do business with.

I can't figure out how they arrived at 12.3 so quickly.

I was at a park in Louisiana, plugged in for days - I drove 7 hours home with the fridge on propane, and that night they were at 12.3. I ran the fans and lights while we unpacked, ~ 3 hours. The net morning we went to unload the fridge, and the meter still read 12.3
We unloaded the fridge, turned it off, hit the store switch.

So what boggles me is that in a 7 hour drive, the batteries went from fully charged to 12.3, yet over night and after 3 or 4 hours of battery use, the next morning, the level didn't drop at all.

Batt level

What are you using to check the batteries? You need a good quality multimeter one of those $30.00 jobs will not give you repeatable readings I bought a Klein about $100.00 at home depot, fluke is the other brand you can depend on they run $160.00 and up. If you are going to be an airstream camper for a good while it pays to have a good multimeter. Keeping batteries maintained is not hard but does require keeping an eye on there state of charge. It took me two sets of batteries to learn the proper battery care. I got 4.5 yrs out of the last set and they were cheap ones from auto zone I now have two 6volt golf cart batteries run in series they are great with the new 3 stage converter/charger I have about 30% more battery capacity and I can leave it plugged in and not worry about over charge. Prior to the converter/charger install I used a portable 3 stage charger works well but a hassle to do and keep an eye on weather. Good camping Rand

Voltage meter

Those meters they put in AS's are a gross measurement won't give you an accurate measurement like a quality multimeter. Like I said before if you will be camping long term you will use it quite often. I also have a plug in A/C voltage meter I plug in an outlet check it after plugging in at campground then turn on the AC to see if the voltage drops under a load. $15.00 at camping world before that early in my camping days had a converter burn up due to open lead at a campground power pole almost lost camper and my dog. Walked in just as it was starting to smoke. Lucky that day but still cost $400.00 to repair. Lesson learned 11.5 yrs of camping you pick up a lot of those most the hard way. Good camping Rand

Your 2015 trailer is under a 2yr warranty and any part not working will be replace free of charge. If the dealer you purchased from is far from you they can always send out the replacement part.

Finally had a chance to run out there with an extension cord. I plugged the unit in and immediately had a red light at the STORE/USE button.

Relay clicked in both directions of the switch, and the battery meter inside read 13.4.

I unplugged the unit, put it back into store mode.

Your LP leak detector draws power even in Store mode and will run your batteries down after a couple of months. I always disconnect the negative battery cable while in storage. I rewired the LP Leak detector to the other side of the relay switch so I should have no draw when in store mode but I still disconnect the negative battery cable in storage.

Well cell batteries usually need a charge close to 14.8v then ramp down as they approach 80% then it takes a long time to get to 100% as chargers will ramp down the amps. With 13.8v with the OEM charger the batteries probably don't ever get fully charged. When the shore power is disconnected the voltage will ramp down to a steady state. My Interstates (grp27) seem to settle down to 12.6 then will come down to 12.4v and stay for there for a long time. Yours are probably grp24 which have less capacity. I always measure at the batteries. I have a cheapo battery meter in a 12v socket and depending what is turned on; lights, fans etc it will always read lower than the batteries. I'm assuming the battery meter on the monitor panel is similar.

My Use/Store switch doesn't have click on/off. Its a self centering switch. The light comes on when pressing one way and off the other but the switch returns to center. When on shore power the light is always on so you can't tell if the batteries have been disconnected. If on shore and and the switch is on Store then the batteries could've discharged more than expected.

You might want to check the battery voltage while the tow vehicle is connected to see if they are getting a charge. You should see north of 12.8v. My trailer, preowned, had the charge line disconnected from the batteries and they never got charged while towing. Fixed that.

Interesting, thanks!

The click I was referring to was the click of the relay engaging or disengaging.
