Hi everyone, I have a Triton 430 (2003) non GT and without battery system. Now I'm changing the refrigerator from trivalent to compressor. The technician will give me a 230VAC/12VDC power supply for the refrigerator only, because the caravan control unit would not support the new appliance. If I want to change the entire control unit in the future with a more modern one, what type do you recommend? Thank you
