We love our 35J. Just got back from a trip to FL for spring break. Currently planning our trip to Grand Canyon and Pike's Peak this summer. We will have 4 kids and a god with us this summer just like last summer's trip to the Smokey Mountains. The bunks are great and you are correct that bunks are only available in the 2013 Vista line from Winnebago.
