Is it better to be hooked to short power in storage? or not?

[trailernovice]

I just found a storage place that not only has covered storage (metal roof/exposed sides), but it also has 30 and 50 amp shore power.

In the past, I've had our TT stored in the open with no connections

Better to have it connected to shore power when stored between uses/trips? or better to have everything (including the battery) disconnected?

Thanks for your thoughts

Summer storage? Keeping it charged and ready for trips? Using it more than once or twice a year? Plug it in.

Winter storage? Using the camper only once or twice a year? Take the battery home and put it somewhere cool and dry, on a maintainer. Don't pay the storage facilities' inflated power charge.

I like mine connected, while in storage, mainly to keep batteries up; though I have managed a couple months of non-use by disconnecting batteries.

It depends.

My 5er alway plugged into 20 amp power any time in covered storage to keep battery charged. And to have power if I needed to do any kind of work or cleaning.
