New 2026 Keystone Montana High Country 311RD — Oklahoma City, OK

Listed at $44,369, this new 2026 Keystone Montana High Country 311RD is a fifth wheel on the Rear Entertainment floor plan. Dry weight is 11,770 lb, close to the 12,195 lb median for the category. At 35 ft it is a little shorter than most fifth wheels (39 ft).

Loaded with water, propane and gear it will sit nearer 13,900 lb, which puts it within reach of a one-ton pickup, ideally a dually. Budget for 15–25% of that through the kingpin, and this is firmly heavy-duty territory and the truck matters more than the trailer.
