John and Zack head to Arkansas farm country to help a couple who have been living on the road turn a school bus into a tiny home where they can settle down. Carol and Charlie have spent years running a traveling pig race at state fairs across the country--and living in a converted semi-trailer that they share with their dozen racing pigs. Nearing retirement, they're hoping to move into a tiny house built in a converted school bus. Can John and Zack give this couple all the creature comforts they've been missing on the road--while completing their first ever school bus conversion?
