I photograph all the surfaces of the actual truck at 90 degrees, straight on. Then size all the photos to 1/43 scale using a color copier. Then I cut out all the various body panels i.e. cab, sleeper side, hood, front grill etc. from the photo copy, coated card stock and assemble them to foam core bulkheads mounted on an existing toy plastic bare chassis. There is allot of cutting and fitting involved. I touch up any rough spots around seams etc. with a color matched water based paint. Basically the whole body is constructed of paper.
