Hi Barry
You, yourself may be able to go along way towards that
It includes:
[1]getting as much good insulation as you can on the top & sides
This will reduce heat penetrating into the fridge
[2]Ensure the fridge is installed correctly ACCORDING to DOMETICS instructions
Very few are
[3]It is important to get as much heat as possible removed from the condensor
Correct baffling assisted by fan/s will ensure that
The aim should be to get the cooling air flowing only through the condensor, not bypassing it ,as much as practical
Idealy the air entering the fridge evaporator should be @ ambient temp
If this is achieved, coupled with improved insulation around 38> 40c will not be a problem
You need to look @ your set for baffling & venting,THAT IS WHERE MOST FALL DOWN
Regarding12v operation they are not advised for 12v operation when the engine is not charging the battery
Dometic make that very clear
With most ,the 12v heater is very much the same heating output as the 240v element,IF IT GETS 12v ,the voltage it is designed for.
Sadly ,do to incompetance or cost saving, very very few have heavy enough cables fron the tug battery to the fridge terminals
If the fridge does not get 12v @ its terminals when operating ,it like most electrical devices, cannot be expected to perform to specs
If you have a multi meter ,it is quite simple to verify the voltage @ the fridge.
Anything under 12v is not acceptable
