The couple who own it go on holiday, it’s a bungalow attached to a field where the caravans are stored. Security fence all the way around and barrier at the front.
We don’t mind it’s closed as we only start heading out for holidays around the April / May if booking
So much of your caravanning experience keeps mirroring mine!
I've got a 2024 Swift, with similar setup to yours. I startled myself last winter by accidentally leaving the 12V system 'on' when I put it into storage, and after just a few weeks finding the battery voltage frighteningly low. My self-installed tracker (Buckman called it cheap and tacky, I recall. But I like it) informed me of that, and it seems like I was in OK time to save the battery.
Incidentally, when I installed and hid my tracker in a genius place, which I don't think anyone will ever find, I accidentally blew the solar panel fuse within the Sargent PCU box that everyone's been talking about.
My secure storage site also locks its gates and prohibits access during February.
