3 Way Fridges

I recently bought a well used 10yo Chescold F40 (F60 similar) and I can highly recommend it. I used it over Xmas in 40 degree heat and kept meat frozen and beer real cold. I understand that new 3-way fridges don't perform anywhere near as well as the old ugly Chescolds.
The only problem I need to address is that the gas flame blows out in windy conditions. I need to make some sort of wind-shield, or just use it inside my car with the window slightly open.
The Repco fridge packaging gives a performance reference, but it only goes down to about 3 or 4 degrees in ideal conditions (~20-25 deg ambient).

As far as I am aware, the only absorbtion/3 way type fridges that come rated in T class are the Dometic upright fridges.
The Dometic/Electrolux ‘T’ rated fridges available in Australia are:
RM2453 120 litres
RM2553 150 litres
RM4601 184 litres
RGE400 220 litres

The RM2350 90 litres is rated as 'ST' but performs virtually up to the 'T' rating.

There is not an electric upright fridge that is T class rated.
In chest type electric fridges evakool is T class rated.
