Westend, I am still digging. The floorplan closest to what I want off the assembly line was the 2010 Keystone Everest 352 fl (front living room). The LR is open to the kitchen, the kitchen compact, the bathroom towards the rear and it had a 12 foot (?) slideout that enabled you to walk to the back without going through the bathroom. Then it gets more challenging. I'd want to add a toyhauler-type gate on the back for a deck and need stairs to the roof. I'm sure more than one person would say start from scratch!
Added: Then again, the 2006-07 Airstream model A with skydeck and bunkhouse layout is pretty great for me too. I like the commitment to the roof level that the big interior staircase creates. Would want to adapt to a 5er though.
