Nice photos and they show some useful extras that may not at first be obvious.
We know about the oven and tall fridge, but what about the Truma Combi heater for space and water. There appears to be a monitoring panel for battery that might, at a guess also control the mains amperage. I can see lashing points under the bed and it looks like the pop top has not been made longer than a Troll .
I'm sure other bits will become obvious.
