I would like to share what we did to have a head in the 5.7 camplite. The 2011 version has two steps used to climb into the queen size cab over. I created a throne in the upper step that is the perfect height. Using a molded seat which I got at West Marine it was custom fitted to the step. There is a perfect fitting bucket lined with bags under the seat. You do your business, bag up, dispose and everything goes back into the step. This works well and you are not cramped in a little box. Being adults about it no one has had a problem. Having a small truck and a small camper you need to think outside the box. Bill
