I have a 2000 Yamaha Big bear 400 professional 10 speed atv. I am looking for a cargo box for the front of my atv and a rear seat or cargo box for the rear. I am snorkeling my atv about 12 inches above handlebars and was wondering which box to get that won't let water in or what can I do to seal the box for deep water. I don't ride deep very often but sometimes where I hunt we go through some nasty spots. I don't want any mud water or dust to get in the cargo box.
