I have access to a CNC router and I’m pretty good at designing in 3D programs but I prefer to use Sketchup because it is possible to make things so FAST. I have started designing a bench seat that folds out into a bed. I know the van seems big now but will get small fast when I start filling it with beds and other furniture items. I designed a side panel for the bench that included an arm rest and I plan on a 3 to 4 inch cushion/mattress. I cut the side panel full size which I usually don’t do, I usually scale the designs to work in .2 inch material and then I make a small prototype and assemble it but I wanted to see how the side panel looked inside the van at full size. I took the panel and placed in the van approximately where the bench/bed will be and it looked too big so I went back to Sketchup and eliminated the arm rests. I then added a reverse side panel, bench seat, back and fold up bed platform. Shown below is a picture of the side panel. It is laying on an interior wall panel I cut out and material for the interior wall panels.
