Hey Ed, there's actually quite a few differences between the two kits. The part # DE66AR is a tandem axle kit for 7k axles that includes everything needed to install disc brakes on a trailer. The rotors are hub/rotors which means the two are integrated into each other. This comes with an actuator and brake lines.

The part # DE64VR is simply a pair of slip on rotors, mounting brackets, and calipers. The rotors fit over an idler hub but the hubs, brake lines, and actuator are not included. What is really nice about this kit is that it is stainless steel which will do a great job fighting corrosion. Stainless is by far the best for this while the # DE66AR has a coating that will fight corrosion but not as well. If there's no saltwater it would be fine. If saltwater is present though stainless is the way to go.
