The ozarks should work fine. I snagged some cooler straps of amazon and that holds a cooler with strap points to the strap points in the rzr bed. It's actually quicker to get out than the lock and ride mount.i got mine in about 2.5 weeks, i was pretty shocked when i got the notification. I was at walmart tonight and happened to notice some Ozark Trail hard coolers that looked like they were designed to fit rzrs... shape looked right, it had the same hold down points as the northstar coolers. i almost bought one just to try it.
