I have a Yakima rack on the top of my Starcraft Spacestar pop-up. It has 5 mounting locations attached to a bar running across the front of the camper. There is another solid bar running across the back end of the roof. It must be close to 12 feet away from the front bar. Have any of you seen anything like it? I'm not the original owner, and I don't know much more than what I see.
