Has anyone mounted a snowmobile on their roof before? I am talking about a suzuki sidekick 4door with an exocage roofrack attached to the frame. Sled in question would be a yamaha phazer 2 to keep the weight down and reliability up. The sidekick is getting approx 40mpg US with a vw turbodiesel engine and 4wd. Power and braking are not a problem. My only concern is the top heavyness of the setup. Vehicle has upgraded springs with stiffer rates.
