1.5 bath floor plans are pretty common nowadays, especially in 40 foot and up coaches. Most every manufacturer offers at least one. Fleetwood offers them in the American Coach (Tradition/Eagle/Heritage) line as well as the Revolution and the Monaco & Newmar models mentioned above have them too. Monaco also makes beaver and Holiday Rambler, so they likely have the same floor plans available. Winnebago/Itasca has 1.5 bath floor plans in most of their diesel pusher lines (Journey/Meridian/Tour/Horizon/Elipse etc) depending on the year.
