Common questions

Are the Express and Savana dimensions the same?+

Yes. They are the same van with different badges, and the cargo dimensions are identical.

How much space do insulation and paneling take?+

The finished figures on this page allow about 1 inch per surface: each side wall, the ceiling, the floor, and the front wall. The rear is the door. A cold-climate build with thicker insulation takes more. In the planner you can choose the build-out level, or enter your own measurements.
