I browsed their blog and they're not just camping, which would be tight enough, but from what I read, they're living in their rig full time! I love my pop up and its versatility, but I don't think I could pull a rabbit out of that hat... They'll need more space, especially as the niños grow. They have a very nice blog.
Yep...full-ish time in a Hawk! I do believe they will go back to trailing something after their initial plan for baja and who knows where else. For now they really want the go-anywhere flexibility of the FWC. These kids are road-life experts so I think they have a good chance of pulling it off. As long as they are following good weather (baja) and using the outdoor space for relaxing and cooking, they only need sleeping and storage in/on the camper.
