I have a 2012 sportsman 550 eps and I'm planning a trip to Maine this spring and will need to be able to carry extra gas. Any suggestions? I have a good size cargo bag on the rear rack but nothing on the front rack. I looked at Kolpin & roto-pax but they are pretty expensive. If someone tells me the Kolpin works well I would probably go with it. However some of the Kolpin reviews I've read say that the bracket for the lock & ride does not stay tight. Any suggestions will be appreciated.
