/diy/ - Do It Yourself

The scope of the project is sort of broad. Tell me if there's a better place to post this.

I'm thinking about living in truck in a relatively cold climate. I'll buy the truck and build the infrastructure (bed, shelves, insulation, etc) myself. I'll use an inverter for charging small electronics while the truck is off. I'm new to all of this. What sort of truck would you get? What sort of wood would you use? A fridge and microwave are likely out of the question, so what sort of diet should I aim for? Can I safely install the inverter on my own or should I get more skilled help? If you did this, what would your setup look like? Any tips or potential problems?

Thanks
