Greg
Dad, 43, an insurance manager who plans everything in spreadsheets. Terrible dad jokes, refuses to use GPS, wants to save on everything and always ends up spending more.
Dana
Mom, 41, a former science teacher. Practical and competitive at everything (games, haggling, hikes), and secretly the one who always wants to go further.
Zoe
13, sarcastic and never without her phone. She runs a travel channel with 48 subscribers, knows every fact about every place and corrects her dad constantly.
Leo
10, with endless energy. He eats every local food (with consequences), collects rocks and bizarre souvenirs and is always in some kind of trouble.
Grams
Grandma Ruth, 72, Greg's mother and a retired long-haul trucker. She owns Big Bertha, drives like a rally driver, tells stories of doubtful truth, sides with the kids and drives her son up the wall.
Biscuit
The family dog, a scruffy mutt who is scared of almost everything, starting with getting into the RV.
Big Bertha
Grams' beige and brown RV from the eighties, with a coughing engine, recurring breakdowns and noises with a personality of their own. Practically a member of the family.
Mrs. Henderson
The next-door neighbour in Columbus, about 70: sweet, but she haggles over everything and knows the whole street's business. She calls Greg "honey".
