Reading through some posts on here it may be that I didnt run it for long enough before leaving home to cool it down properly, the ambient temp in the tent was probably too high (how can you overcome this?) or even maybe it wasnt level enough - is this an issue using the EHU tho?
It does help to run it at home for 24 hours before leaving, plus make sure everything you pack into it is well chilled in your domestic fridge. Once loaded don't open the fridge till you've got it plugged in and running again. If you have a long car journey of several hours and it's hot it helps to freeze some of the contents beforehand, like the milk or orange juice.
It's essential to have the fridge perfectly level when running it on gas but less so on EHU.
As to coldness it's unlikely an older fridge of this sort will manage lower than 20'C below ambient even in the best conditions. If it's 25'C in the tent...very easy on a sunny day...then your fridge will not be any cooler than 5'C at absolute best, which is just on the safe limit for storing raw meats, pate, sausages, bacon etc. Be sensible about this. If you're really concerned take a small fridge thermometer to use inside the fridge. Absorption fridges are never as efficient at cooling and maintaining temperature as a domestic compressor fridge.
It helps if you open the fridge as infrequently as possible. Take out all you need for a meal at once and return unused foodstuffs to it asap, don't let them warm up more than they need to. If chilling wine or beer, cool it down a bit first first in a bucket of cold water with a wet teatowel draped over the bottles. Don't put warm foodstuffs in the fridge. If bringing chilled food home from the supermarket invest in an insulated shopping bag to keep the food as cold as possible on the journey home.
Finally, keep a good airflow going round the fridge. If running on gas this is doubly essential as all gas appliances need good ventilation, so keep the fridge in the porch. If on EHU keep it in the driest area of the tent, a little up off the ground if possible. You can't control ambient temperature in the tent by any other method than good ventilation, which only helps a little. On very hot days the fridge will struggle to even remain cool, let alone cold.
You can buy newer models that can chill to 30'C below ambient but they're more expensive of course.
