Structural members are releasably secured to the snowmobile, and a tarp covering is placed over the structural members to form the collapsible shelter. The seat or seats of the snowmobile form the seats of the collapsible shelter. The shelter may be erected at one location, and moved by the snowmobile to a new location.
