Yes, this is normal for absorption fridges.
keys are:
keep fridge side of camper on the North side, in shadow, this helps a lot.
The fans will help.
The construction of the space behind the fridge should force all the air over the coils, not around it. There should be a baffle or something so all air goes by the fridge parts.
Inside the fridge the fins need air circulation, so dont push the bread or bags up against the fins.
If more insulation around the fridge box is possible then add another layer, or check that there is good insulation around it already.
