Erin and Chad have expanded their family with twin pygmy goats, but having extra "kids" means more household chores. So Gil and the younger kids stop by to help Chad paint the goats' new shed. Back at the Bates household, Nathan's impromptu zip line wasn't the safest, so Gil and the kids reconfigure a longer and much safer design. Once they settle on the perfect spot, the kids test it out! And later, Erin surprises Chad with a 30th Birthday Adventure with an escape to Hot Springs, NC for a romantic getaway without the kids.

The Bates family will never forget their house fire, and so they organize a car-washing fundraiser to give back to the heroic volunteer firefighters who responded to their emergency situation. Right before the big day, Zach insists on giving the Bates kids a tutorial on the do's and don'ts of properly washing a car. But will a family water fight put an end to Zach's lesson? Meanwhile, Chad and Erin are interested in purchasing a "fixer upper" house and begin the search for a property that they hope to renovate and call their own!
