For food I cooked using a gas type stove or I also had a portable rice cooker type thing that I could cook rice as well as soups or stews or that type of thing in.

Cleaning I used a combination of a gym membership to a nationwide chain and used their showers, used family members showers if I was near to them and sometimes I'd have a baby wipe shower if I was really in a pinch and needed a basic clean.

Entertainment the same as I do in a house but just in a lot more energy conscious fashion. I run and cycle a lot so that was easy and I could run a lot of different places.

I had a small solar panel as well as the alternator charging a decent sized battery setup that I had hooked up to USB ports as well as a power inverter to convert to AC power so that way I could charge a laptop as well as devices.

So I had my phone to watch videos or listen to music on etc and then a laptop I could play games on or ran my DJ setup reliably. I had many options, I just always had to be conscious of batteries. I'd always have the laptop charging whilst I was on the move as the engine would make an abundant amount of electricity and then I could charge the laptop a few times if needed from the battery or trickle charging from the solar. So yeh, I had plenty to do.

I also smoked a lot of weed in combination of those things xD

I miss that life tbf, houses are over rated but it is also nice to always have a hot shower and stuff. Advantages of both
