Believe it or not I purchased the low profile gas can/set up from Ski Doo and bought the side mounts from Yamaha that are found stock on the 08 and 09 models. All in all the total cost was close to $100 bucks but well worth it. The gas can's low profile has kept everything in place and the side mounts are easily adaptable to hold anything. I believe the gas can ran around 60 and each side mount was 20. I've carried snobunjies, gas, backpacks, etc. on this setup. Hope this helps
We use QRS - on sleds and atv's; then you can transfer cans/bags all season. Depending on the sled's heat exchanger, you can get 2 mounts on most tunnels. Derek
