Sun Valley Inc. has introduced its first sport utility towable (SURV) – the Rattler, a wood-and-aluminum travel trailer in 24- and 27-foot floorplans. “It’s entry level, but its got the nicer stuff in it – a rubber mat instead of linoleum, upgraded hinges, LED brake lights and 5,200-pound axles,” said Mark Romanetz, president of the Elkhart, Ind., towable manufacturer. “We want to stay with smaller trailers because that is where our niche is. Not a lot of people are building small toy haulers.” The Rattler features an open floorplan with free-standing tables and sofas that fold up against the wall. Retail prices start at $21,000.
