The Uhauls originally had 11 different cushions, this is counting the front bunk. Quite some time ago I found an illustration showing their placement but can't find it now. In the document center here on the home page you can access the parts manual, the repair manual, the operation manual and other information. This is also on the Facebook site under "files" at the top of the page. In the document center here you go to the bottom of the page to the list of trailers and click on "Uhaul" then the list of documents will come up. Depending on how you are using the camper will determine what you need for cushions. We just use the front for seating, rear is one solid piece of foam for the bed. Like Gage says, foam cuts real easy with an electric kitchen knife.
