Here is a picture of a trial floor arrangement, of which there were many.  We loaded and unloaded the  components many times and moved them from one spot to another before deciding on their final locations.  We needed the visualization, plus we needed to know that everything would fit.  It is very important to be totally self contained as we plan to boon dock. 
We chose not to rip out the floor as other conversions are done.  We covered it with 5/8 inch plywood.  It was well into the project when we realized, much to our surprize that there was a difference of about 2 1/2 inches from the back to the front of the coach. This had to be taken into consideration as we worked from back to front.
