About Caravan
A caravan has room for everything, and the mistake is using all of it.
The bank can be big. The inverter can be big. The fridge can be a full upright. Powered sites turn up often enough that mains charging matters, and the roof takes an array that would cover a 4WD twice over. All of that is true, and all of it is a reason to size the system to what the van actually draws rather than to what the space allows, because a system built to the space is a system that costs twice what it needed to and still runs out on the cloudy week.
The alternator is the other caravan problem. It is at the front of a tow vehicle, and the caravan battery is a long way behind it, through a plug on the drawbar. A DC to DC charger in the van, fed through a cable and plug rated for its input current, is what gets a proper charge across that distance; the charger does not make an undersized feed adequate. How much the bank picks up on the drive depends on the vehicle, the battery and the distance.
Air conditioning belongs on a caravan more than on anything else here, because a caravan sees powered sites and has the roof and the weight allowance for a rooftop unit. Where it goes, the battery and inverter are sized around it rather than added to.
Then the rest. Roof vents and fans for the nights without air conditioning. An upright fridge with a proper mounting frame. A distribution box with a fused output for every circuit in the van, and a monitor by the door where it gets looked at.
