Time has come, after our last 2 week trip with one fridge (50Lt Ironman) we were convinced another fridge was needed. The fight over food v drinks was too much.
Bit the bullet & got an Engle Eclipse, very pleased with the performance, got down to 2'c very quickly,not as quiet as the Ironman but this will not be an issue.
Of course will now need another panel as a 140W panel & 2 100Amp batteries might struggle. Of course then a new controller etc etc etc....................
