There are several reasons I wanted to go with a shipping container. They’re cheap, strong as hell, and most of the fabrication is already done. All I have to pay for is modifications. They also offer better security since they’re not the easiest things to break into. I can always install security cameras instead of windows and a steel door. I picked a 20 foot length because I intend to make it 16 feet with a 5 foot bunk over the cab. Even with solar panels on the roof, the dimensions would be: 21 feet long, 8 feet wide, 11’ 10” high. Another reason I wanted a container is because I wanted the strength of a steel tubing internal cage without the added expense. I have nothing against aluminum providing someone can show me an aluminum body with an internal cage for the same price as a used container. I’m also looking at buying a used Isuzu or Mitsubishi flatbed truck for the container to sit on. Once again, cheaper than a new one. I can probably deal with the higher weight load by choosing a truck with a GVWR over 20,000 pounds. I know it’s a pig on fuel but I won’t be driving it very much. Mostly it’ll be parked on the street in an industrial section of town. I also don’t want it to look like a camper van. I want it to look like a super tough moving truck so that people leave it alone. Also, a vehicle length of 21 feet is the legal limit for parking in the Vancouver lower mainland area. In other words, the ultimate urban stealth camper.
