I've tried finding a thread on this but am coming up short. We are looking at getting either a 16' Scamp or a 17' Casita. We both like the side dinette layout with bathroom but also the bunk feature of the sofa....Has anyone figured out how to do both? If so I'd love to hear about it of see pictures. We don't have any children yet but are trying to plan long term so we can put off out growing the trailer as long as possible. Thoughts suggestions?
