If they're delivering a single unit from the factory to your door with a round trip that's a pretty reasonable price regardless how silly the product may be.

The median population center of America is around Indiana, so the average delivery charge will be ~3k. The total delivered cost with tax will be about 30k.

Also, there is a threat of municipalities, including states, suing the manufacturer for selling manufactured homes that aren't up to code. While the cases may lack standing or merit, they have lawyers who can make it very expensive to stay in business regardless.

At that rate, living in a Jupe will be a necessity.
