The interior usable living space in the Bajacamper is 131.52 square feet! That's huge! The storage areas total 42.92 cubic feet, which is more than enough for 4 people's gear for 12 days in Baja. It is designed to have 12 large plastic storage bins underneath the floor. We've had 8 people comfortably socializing inside the camper. It is 11 feet across the inside from seat to seat.
