Best practice for putting my caravan back into sto

1 .... depends how long you're leaving it. If a few weeks, then no. If a few months, then yes would be a good idea.

2 .... more recent caravan generally have some kind of 'OFF' switch near/over the door.

3 .... assuming your car is fully wired up properly, then yes, it'll charge as you tow

3. As well as when hooked up to EHU.

Off tack a little, do you have a cover. If so then I'd throw this on if you are not away for a few weeks. It may sound a faff but it is a damn site easier to put on than it is to clean your van.

Agreed ... I missed that bit .... 🤷‍♂️

2. Ours has two off switches, one at the fuse box and one above the door, if the one at the fuse box (labelled system) is off the one at the door is always off. The system one also controls two other off switches, one for the charger when on EHU, another one for the space and water heater. The car charging will happen even if the system switch is set to off, well it does on ours.

Is it good practice to switch everything off, I have no idea but we always do. Do you have a tracker or alarm system that needs power? (we don't).

Our tracker was independently powered 

Your instruction book should explain everything, Peewac.

In addition to the electrics you need to consider the water system, which needs draining down, which I failed to do this last winter and was caught out with the casing split where the pump enters the caravan, costing me an expensive repair for a new truma pump housing.
