Most trailers have slides,most slides are on driver's side and most slides have windows all the way around. Problem is you must sit in chairs facing the sofa to see out them. Many people remove the sofa so that recliners can sit in it's place. You would have to special order to have a door on driver's side and even then I believe they must also put one on the curb side. You might brouse mfgr's web sites for floor plans. NuWa owner's forum for instance has all models from 1999 foward in the arcives section.
