EDIT 2/19/20: So this option has been fully played out to be a no-go. Thank you all for indulging my obsession. See post #21 for my climb in and try it results. While on the road driving to a multi day drive destination, has anyone ever slept inside your pup w/o raising the roof (at all)? We have not yet taken a long distance trip where the destination was more than a one-day drive away. But we have one in mind to the Grand Canyon at some point. So I was initially thinking of how I could pop the top up a little, and slide one bunk out just enough for the two of us to sleep overnight and continue driving the next day w/o actually setting the pup up (creating a bunk support inside and out). Yesterday, I decided to see if it would be possible to just open the door, leave the roof clamped down and sleep on the floor. The answer appears to be YES! For our 10' box '99 Starcarft Stardust, the folded over sink leaves enough leg room height, but the back splash supporting it on the floor splits the legs' area in to 1' and 2' wide spaces. So... When we know we are going to want to non-setup sleep in the pup on the road to our far away destination, I realized that, before leaving, I could easily remove the back splash (≈ 7 screws), create one or two supports out of 1x3's. One piece across the top supported by a 1x3 leg against each side of the pup interior to support the weight of the folded over sink. We arrange cushions on the floor, roll out our sleeping bags and sleep, albeit cozily in a 3' wide by 75" long floor space. We can even lock the door from the inside. We could stop at a designated campground, truck stop, or residential area and be very secure. Depending on how safe other options like a Walmart parking lot feels, that might be an option too. (and always thinking ahead... How would this work for the 2007-2008 Fleetwood Sun Valley (12'box) that we hope to move up too when we find a good one? My best estimate from the floor plan in the '07 brochure is that with our heads towards the 'U-couch', I'd have 72" from the bench seat to the folded down sink/stove. On the door side, my wife would have 59" from the seat to the entry way cabinet. Oh, and the sleeping space with would be a roomier 4'2" ! !
