Looking to switch the sacs out in the back of a Mondo and was wondering if there is a set of bags that will fit in the back lockers that are made specifically for the Mondo yet or will any old 750 bag do. And does anyone know what size the bag in the center is on the Mondo?. I know the 1300 pound ballast is standard but I don't know how the weight is broke up between the 3 bags. Thanks in advance
