Wow!! I guess at the Indy RV show, on thru Sun 19th I saw one of the most notable inovations in 5th wheels! the upper level in a Prowler/Fleetwood, was that it has a living room and (artificial)fire place up there and the bath/bedroom in the back! very nice! a small slide up there for the couch. A lady from the dealer said it is the first time it has been shown. the trailer was in the 30' range.
Indy RV show The Terry line had this floorplan several year ago, but the one we looked at did not have a slide. Really liked the floor plan. Best I can remember the hight was around 6 ft.
