• The couch pulls out and lifts up like this.
  
  
• It's about 60 inches square. I'm 5'11" and can sleep fully extended on it if I sleep diagonally. I also have a foam pad that I can put on top of the safe for additional leg room. I usually sleep in a hammock though.
  
  
• I can stand up fully. There's about 6'4" of head room in the center of the van. My friend is 6'3" and finds it to be a bit cramped.
  
  
• Electricity is provided by four 100W solar panels on the roof and three 100Ah batteries up front. This powers a fridge, a vent, lights, and outlets. I have 12V car outlets and USB outlets. For odd proprietary plug A/C-only devices I have a little inverter.
  
  
• I have a little fridge. I left space for a propane tank in the big cabinet and will probably get a little propane burner at some point.

Laptop charging.

In the mean-time I've seen this recommended for the Tesla because it lacks fan noise.

For example, this would be something I would use in the US. I haven't done any research on what inverters cost for European power types (220V 50Hz). Obviously, the product I linked is for American appliances and devices that use 110V 60Hz electricity.
