Here are a couple of rental camper cars that I spotted in Lorne, Australia.....a little beach town off the great Ocean Highway....
The rental company is apparently called wicked campers...tent on the roof, gear in the back, interesting slogans/tag lines on the sides....
The writing on the red one may be hard to read; it says "hey kid's roll a doobie for Scooby" on one side (with a picture of Scooby-do) and "I'm a street-walking cheetah with heart full of napalm" with Iggy Pop on the other.
