This is my method, when starting projects like this I build models using the scale of 1 inch equals 1 foot. Go to the toy store and buy 2 action figures, they are about 6" tall. You can use cardboard, but I use cereal boxes. I cut them 4"x8" or to the scale size of a sheet of plywood. If you want to account for wall thickness you will have to glue pieces together, but I usually ignore that. On a deer lease portable cabin I use cardboard, to account for the walls.
At first you can make the model using cellophane tape and a little glue. If you want to keep it, paper mache with a layer of newspaper and paint on the outside. Use watered down Elmer's white glue instead of the water and flour mix for the paper mache. By using a little tape I can change the design with just a simple craft knife cut.
If you want to construct the trailer, you can cut pine into the proper sizes on a table saw, or the easy way is to buy balsa wood at a craft store, Really want to get fancy, the body can also be made out of craft plywood, also available at craft stores. A GI Joe toy can provide you with the wheels.
By keeping notes, every piece of the model is noted on as to size etc.. Cost is minimal, any changes you want or need to make can be done before you start cutting that expensive wood.
