Storage question.

We are lucky enough to have inside, climate controlled, secure storage in a warehouse. Is it better to leave the trailer plugged in to 110 VAC while it's sitting, or to leave it unplugged from power with the battery disconnect switch off?

This is what I do, but there is no perfect answer as it seems methods vary.
I leave my trailer plugged in for a couple of days then unplug and move power switch to storage. In a few weeks I plug it in again and repeat as long as the trailer is in storage.
These trailers have a constant drain on the batteries from the electronic systems.
If you plan to leave the trailer for months at a time without plugging it in , I would would disconnect the batteries at the terminals so they will not have a drain on them.
I don't like to leave the trailer plugged in to 110v all the time as I don't trust the charging system and would not want to come back to boiled over batteries or worse, fire.
With all that being said, some folks do leave their trailers plugged in 24/7 and have done that for years. But, I assume they check on things frequently.

We keep our unit indoors, also. Not climate controlled, but dry. (It's a MH, but still has batteries that need to stay charged.) Over winter, I use the battery disconnects and hook up the battery tenders.

During the camping season, I do not usually plug in to 110v AC between trips unless we are not going out for a while. Then, I might plug in a day or two ahead of an outing just make sure the house batteries are well charged.

I also installed a battery disconnect on the negative terminal of our house batteries that I often use. There are things on the MH, as there are on TT's that tend to draw current, even if the battery disconnect inside the TT or MH is used.

I know this may be confusing, but hang in there, others will chime in and you'll get a routine down.

Unless they've changed it, the converter Airstream uses is a cheaper one stage and can boil off water and overcharge the batteries. You need to remove the batteries when stored and attached to a three stage charger.
