my question would be what are you trying to store on the ATV>
a 4 inch tube ain;t going to hold all that much, everything will end up having to come out MOST times to get the ONE thing you wanted out LOL
most folks I think like Army Ammo can's due to there water proof, easy to open and close and well rather easy to come by and not so costly, water proof, can be mounted pretty easy, a lot of good reasons they get used so much??
a water proof duffle bag is also a easy deal, can be held on with bungee cords or a ratchet strap, hold a lot more things maybe??
but again, comes down to WHAT your trying to store on the ATV
