Beautiful Thor Four Winds 31W.  2014 bought new in 2015.  14,000 miles however 3 long trips (St. Louis, MO to Yellowstone NP and two trips St. Louis to Destin, FL for a total of 5,600 miles).  However, what separates this unit from almost any other you will look at is that it has been stored inside.  Not outside or just covered but full inside storage.  Additionally, because it has been stored inside it has also been stored on it's jacks so there is no negative effects on the tires from the weight, the ground, or the elements.
