[mudder fudder]

I have mine mounted in the dry box as well. If you are taking your ATV swimming, it will get water in there, but basic mud-riding, there won't be a problem. Just run a bead of silicone all around the seams, press it in with your finger, let it dry, do it again, let it dry, and then, for extra security, slap some grease on the top of it to keep the terminals from corroding. You may have problems eventually, as with any electrical device that goes in the water, but you bought the best winch as far as I am concerned!!
