There was a High Country across the street last week. It had 6K axles, the Helium Technology construction, to me that means it was a lighter built unit.
We spend about 8 months annually in our Montana and feel the extra weight, the better quality cabinets, larger/heavier frame, larger brakes/axles is a better option for us.
We are way past vacation units, kids in school, and making payments. When we bought our '14 3150RL with dealer installed Splendede and Mor/ryde X Factor was back of 50K out the door and was a year ahead on model dates.
