Hi! Thanks for your question.
Yes, there is pushback about using wood. In our case we are choosing both worlds. As an Architect I have used wood, plywood and other composites. It is important to understand the technical data of each product from the manufacturer and ascertain whether it is appropriate for the application. In our case the exterior envelope is a full composite construction. We chose a composite because it is lightweight, durable, strong, rot resistant, and excellent thermal properties. For the interior we wanted a softer, warm aesthetic, ie a modern log cabin. All interior plywood is cut on our in-house CNC machine, keyed together and glued creating a strong but flexible joint. The interior plywood is also finished with a high end wood finish called Osmo. It is durable and infinitely repairable.
The price is approx $78K depending on options.
We are using the Redarc Total Vehicle Management System, and since Redarc recently introduced their inverters to the US market we will be switching to them. By using a sole manufacturer this improves the integration of the components in the camper.
