The upgrade is expensive with 2 separate compressors plus the cold plates take a lot room the box (s). Caulder does a good discussion of refrigeration in his book "Boatowner's Mechanical and Electrical Manual: How to Maintain, Repair, and Improve Your Boat's Essential Systems. He basically says that the DC evaporative plate systems are hard to beat with the small size, efficacy and reliability.
