I didn't see anywhere that you indicated what size unit you are looking for. We had a 2005 Citation Supreme 28.5 RKS that we bought new. It was a true 4 season unit with complete winter package including 2 stage furnace, thermopane windows, etc. It also had 2 dual pane skylights which made it a very bright and open unit. It had one main slide in the kitchen & living room but did not have a bedroom slide.
Citation/Corsair fifth wheels/trailers/truck campers were built by General Coach in Oliver, BC, Canada and were extremely well built, durable units. They had several rear kitchen fifth wheel models including many with bedroom slides. Unfortunately they did not survive the economic crash and closed in 2009.
We loved the trailer but wanted a larger rear living room model. We did buy the same brand, however because they are so well built.
