His Frig has a problem. 17 years old and using to much power. Most likely gasses had crystalized.I appreciate the graphs.
Can you tell me how many WH per day your new fridge versus the old fridge? Looking at your graph my estimate is 8 kwh per day with the old, and less than 1 kwh with the new.
I have a propane fridge running in electric mode right now ane the temp is comfortable 65 F outside. My fridge uses 350w to 400w when on, and when I run it on electric, it takes 5 kwh to power it. I think in the summer the fridge would use much, much more power.
Your 5kwh per day is about 208w per hour, about 50% duty cycle.
In the summer Air Conditioning makes a difference. 80F on 3 sides worked on my old A-frame camper.
Boon docking in the AZ mountains, with no AC, in 90-100F challenged the frig. I added ventilation fans in the vents for back of the frig. Also the freezer worked great, so I froze Blue Ice and would move it down to the frig part for midday. Also helps to have some liquid ballast (beer) in the frig.
IMHO: Absorption Frigs are not efficient, but they will run on propane
