Since I dont have a trailer hitch, I spent about $20 and modified my existing bike rack to hold a Yakima powder hound. This keeps the roof rack open and allows me to carry 4 people and gear to the slopes. Thought I would share my solution to that problem. Those are steel components and grade 8 hardware linking the 2 Yakima products, so I'm confident with the safety. Similar setup to the mopar rack.
