Last night I slept in the van. It was a friends birthday, and after going out we stopped at the van to eat our food. Then they went home and I slept in the van.
It's a brilliant mobile bedroom, with kitchen and ensuite bathroom. I installed a heater during the week, and we were able to have it on whilst eating.
Staying in the van cost me no more than driving it over, which cost me no more than driving a small car.
I love my van.
