A hunting vehicle incorporates a roll cage having a tubular frame member. A gun rest incorporates a standard mounted on the tubular frame member and provides a support moveable up and down on the standard between a plurality of supporting positions. The standard is mounted on the frame member so a hunter may place a rifle on the support to steady the hunter's aim. The standard is mounted on the tubular member for easy rotation by the hunter so the hunter may aim in a wide arc without unfastening or loosening any fasteners and without moving the vehicle.
