Most of the time I run around 300 foot elevation. Occasionally, I run in areas around 3,000 feet but thats rare. I am running a 1.75 inch track. Mostly my riding consists of trails, swamps, rivers. While I run trails, I like to get off the trail whenever possible and play in the deep stuff, but no mountian riding. Sled wieght would be about 210 lbs including rider. Since its a polaris kit, I have been told (this website) that I will need to run the standard idler wheels. The dealer has not confirmed this.
