Peru, Ind.-based RV manufacturer Riverside Travel Trailers Inc. for 2012 has introduced a double-slide, 36-foot drop-frame travel trailer floorplan (32LOFTRB) with a pair of stacked rear bedrooms — one for kids with 49-inch ceilings and an upper loft with a slideout that has 6 feet of headroom for adults. ”It’s like a backward fifth-wheel,” said Mark Gerber, Riverside vice president of sales and finance. ”You step down to the kids’ room and you step up to the adults’ master suite.” The wood-and-aluminum Riverside travel trailer floorplan features a larger front kitchen and expanded living area, Gerber said, because of the space saved by stacking the two bedrooms. ”You’d have to have a 42-foot trailer to get all the stuff in it that you can by stacking the bedrooms,” Gerber said. ”You could put a 42-inch TV in the rear bedroom for the kids so they could play games or watch TV.” MSRP: $29,000.
