Overview: The focus turns to functionality as the remaining competitors are challenged to design and transform a Chevy Express Van into a unique mobile vehicle for a small dog-grooming company. The designers must not only present their vehicles to the judges, including guest judge and celebrity dog training guru and business owner, Tamar Geller, but also put the vans through a real-world test at a public dog park. Brooke Burns hosts and Jean Jennings and Harald Belker serve as judges.
