I am going to Italy in August and would like to know what is the moste effective way to cool your fridge, Gas or 240v? I went to the same place 2 years ago and temperature reached 38 degrees and my fridge's cooling was usless. Milk went off after a day. Some seasoned caravanners told me to take the vents off the side of the van to increase air flow, this improved the cooling slightly. That was on my old (1998 TEC) van so hopefully my new one (2009 Hobby) will be better and just in case I have hired a fridge at my pitch for the 8 days. Is there any difference in the cooling with gas or 240v?
