Why it matters
Three honeycomb boards make a flat bed across the back seat and footwell. Chumajor lists a six-layer build with 600D Oxford, support for up to 400 lb, zippered side flaps that cover the doors and a mesh window. A seat belt, two hammock straps and a storage bag are included.

Pros and cons
