I have a sled for sale locally and someone is interested in trading a 2015 Timbersled LT kit for it with some cash but I think he is valuing it a little to much. Are there big differences between the 15's and the 16/17's? I don't mind running an LT kit in fact I think it is more suitable for the riding I would be doing. Just seeing what you guys think an approximate trade value is on one of these kits
