The tracks that I believe will work the best are the Mattrackers -- I've spoken with both companies - both provided really good info. Camso track are in the 5K+ range and will require some modification to my RTV (nothing dramatic - just clearance stuff). The Mattrackers are almost double the price but have a suspension system so that each track conforms to whatever is on the ground, plus the price includes custom brackets for the RTV and they have customers and references that have used there stuff on my RTV x1100c. The Camso rep wouldn't answer my question directly as to whether they have an knowledge of their tracks on the RTV x1100c. Is Mattrackers worth double the price? no clue.
