Need to spend 20k and make your car look uglier??? I present to you: A Prius with a camper added to it. The camper allows a total of 4 people to be able to sleep in this vehicle, and adults can stand fully upright. I cannot find any info out there on what this does to a Prius's mpg- obviously has a negative impact, but is a cough stylish cough and aerodynamic design... link
I feel like shit for getting duped into the lithium battery "upgrade" that only works well in 60-80 degree weather. Been getting like 38mpg all winter. Probably fine if you live in southern California.
