Keystone MontanaKeystone RV Co., Goshen, Ind., has added three lighter ”Helium Technology” floorplans to its popular Montana high-profile and Cougar mid-profile fifth-wheel series. ”We looked at roofs, countertops, frames, sidewalls and found new ways to do it with new materials without sacrificing quality and features,” said Aram Koltookian, general manager of Keystone’s Montana/Cougar Group. The ”Helium” construction process removes up to 1,400 pounds from the standard Montana fifth-wheel, the company reports. For instance, the 33-foot four-slide Montana built with ”Helium Technology” featuring Azdel SuperLite sidewalls has a dry weight of 9,400 pounds. Base MSRP’s for the Montana Helium are in the mid-$40,000s. At the recent Louisville Show, Keystone also introduced the redesigned Premier by Bullet ultralight travel trailer in 19- to 35-foot lengths, including a 31BH floorplan with an elaborate outdoor kitchen and entertainment center. MSRPs start at $16,500.
