From experience
Inverters and residential fridge are less prone to failure than absorption RV fridges
And if one fails and is warm inside when you open the fridge
Then you should have enough sense to not eat the food
That engine cost a lot more than some food and a new inverter
The comparison is not valid
You did not have much option regarding engine replacement, unless you were willing to replace other parts of the drive train
Putting in a residential fridge does require additional items, inverter batteries, that may not be pre-existing
But the comparison is just not the same
And a failed inverter is not going to be leaving you stranded on the side of road, oil all over the ground,
Totally different circumstances
Coincidentally I have had both fridge failure and engine failure
The Fridge was remedied in a matter of hours, the engine
Took weeks both times
