We started our ceiling early because Addy’s Uncle, Rodger offered to help us make our custom cabinet for against the big wall/bed area. The cabinet will range from the floor all the way to the ceiling, so we wanted to get the first 3 tongue and groove pieces fixed in order to get an accurate measurement.
We ran all our wiring up and through the central support beam that runs up the wall and across the roof of the van. For the wiring, we used 14ga red and black house wire (intertwined them by twisting with a drill) as well as T-Connectors to make the parallel wiring easier.
Our Tongue and Groove ceiling pieces were pretty expensive, the entire ceiling worked out to around $250. We went with an ebony stain and used a conditioner before staining each piece. We also painted the unseen side of each piece to protect from moisture damage.
I fixed 1×4 painted supports to the interior structure using self-tapping 1.5″ stainless screws. This would be the structure that we fix our first tongue and groove panel onto.
