G'day Wartim,
I've got a RF60 Evakool Fridge /Freezer (white fibreglass)..... and I'm very happy with it, pretty sure it doesn't fit a 2ltr softdrink bottle as they are just a little too tall standing up..... not really a problem though as i don't reckon i would ever take up 2 ltrs of room from the esky with a big bottle of softdrink, would rather carry a carton of cans, and cycle them through the fridge a few at a time..
I reckon the Fridge Mate units would certainly handle the heavier knocks, but i went with the fibreglass as mine wil be only ever in the back of a Cruiser Wagon or sitting around the CT kitchen, also mates have owned the old Evakool ice boxes and reckon they were tops.
Also, they are made in Aus, and from everything i've heard the after sales service is great.
