My Dometic DTU16 kicked the bucket this year. Replaced it with the CT16. Great price, and the sales guys were real knowledgeable, helpful. The CT unit kept my boat cool all summer, worked like a champ. Will be testing out the reverse cycle soon.

I bought this unit as a replacement for my cruisair VTD 16, and I am very pleased with my selection. Great unit and lets me use my old thermostat and cable.
