Brought home the arctic fox 25P from Sumner Rv to Wenatchee. Two mountain passes and a total of 160 miles. The Tundra did great and averaged 55 - 65 all the way. Gas mileage was not the greatest, got about nine miles per gallon according to the computer. Dry weight is about 6700lbs. Used a wdh. People at Sumner RV are great to work with as they set up the hitch and also the P-3 brake controller I installed. Hope to get a little better mpg when not going over the passes.
