My family and I bought a Ford Transit last spring, and it felt like a dirty secret. Despite being a relatively svelte RV, the typical Class B camper gets 16 to 20 miles per gallon and emits far more greenhouse-gas emissions than my Prius or bike, both my long-preferred modes of transit. Vans are traditionally converted using toxic materials, such as foam insulation, chemically treated plywood, vinyl, and various other plastic parts. Surprising, right? Scrolling through thousands of #vanlife photos, one might have the impression that it’s a vehicle for woke nature enthusiasts and families raising the next generation of Greta Thunbergs.
