Our Thetford T2160 Fridge freezer which was fitted as a replacement for the Domestic Tec Tower last year seems to be coping well with the current high temperatures here in Berlin, the internal van temperature was 39°C last night when we got back at 9pm, the freezer temperature was -12 this morning but during the night I reduce both the fridge and freezer settings and run it in 'Night' mode to save battery capacity. Before leaving the van this morning the freezer was set on high to take advantage of the solar, this evening when we get back to the van I'll check the freezer temperature again.
