If you have an ATV, Quad or 4 wheeler this is the most functional rack solution I have ever found. Best of all its cheap and easy to make, but strong and multi functional! I have tried rack bags, rack baskets, rack storage boxes before but none of them work as good as this home made set up for your atv, quad, and 4 wheeler cargo racks. You can fit a 5 gallon bucket plus extra gear in each of the crates. The system is rock solid and super strong. Its waterproof and easy to clean. This is the most functional rack solution for quads, atvs and 4 wheelers.
