A student version of Autocad can be downloaded free. Autodesk Architecture can be downloaded free too, and it's got 3D objects (furniture, walls, appliances, etc.) that are drag-and-drop. The problem with Autodesk isn't the price, it's that if you don't already know it, it's difficult for most people to learn. It's not all that user-friendly. Google Sketchup is free and easier to learn, IMO.
FWIW I created a 3D model of our bus in Autodesk Architecture, and while it sorta helped us roughly plan our build, we found good old fashioned graph paper and (to scale) paper cutouts of furniture/appliances to be more useful. In the end, though, the bus itself ended up telling us how to build it. Once we started putting the physical objects in the bus, we found out what would work and how, exactly, it would all go together.
