Abby has a diesel F-350 with a horse trailer attached--she's converted it over time into a sort of camper, which holds her belongings, things she trades with, supplies, and sleeping stuff.
Meg share's a large tent with her husband and son, they drive a beat up old Chevy pick-up.
Margot has very little belongings, and is currently sleeping in Louisa May's van. She needs to do a lot of scavenging.
