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

I disconnect and shut everything down between trips, unless it will only be a week or two before the next trip. I disconnect the battery when not using the TT. I usually reconnect shore power about 3 days before a trip, and that is enough to get the battery charged up and the frig cooled down and filled up.

I know people who leave everything hooked up all the time, and it works fine for them.

I think it is whatever you want to do.
