I did some searching and didnt find the answer. I have a 2012 XP4 900 with a spare tire mounted on the back. I purchased 2 fuel tanks by Roto-Pax that I can either mount on the roll bar against the rear behind the seats, or on the side in the back, or maybe even mount it to a storage box. I am wondering what else I can fit as far as a nice Cooler and storage box that I can secure. If I cant have both then I will use an insulated cooler as storage when not in use. How about a Pelican? If I am doing this right you should see a photo
