I put my gas can on my 07 a few weeks ago. I put grip tape on the tunnel to prevent rub marks on the aluminum. I have five days riding on the sled and pretty much shredded the grip tape and the gas can left grooves in the aluminum. I previously had an 04 REV, and it had a rubber mat on the tunnel. Checked with the dealer and its $50, little much. Just wondering what most people have done to prevent bad wear on the aluminum?
