Thule Ascent 1700. I bought this used about 5 years ago, and only used it once. In good cosmetic shape and comes with 2 keys. Opens and tilts both ways so that if it's mounted to the center of the roof it can be accessed from either side. This thing is big, measures approximately 90 inches long and 36 wide. The front hinge/stay that holds it open sometimes pops off the ball socket, but doesn't affect opening or closing. Looking for $300 and a local sale as shipping this will be expensive.
