I installed a pretty neat system for my girls 5th gen. She does the overlanding thing. The main battery is a group 31 that works fine. The second battery is a Bioenno LifePo4 100AH battery connected to an MPPT charge controller and a hard glass solar panel (flexy solar panels all die within 3 years so forget those things). The solar panel charges the aux battery and runs the fridge when the car is off, but when the car is started, a relay takes control of all of the loads in the car and the panel continues to charge the aux battery. When the ignition is switched off, the system uses the aux battery for the loads. She has a CFX50 and uses it in 105 degree temps, so it draws quite a bit more than people who have fridges in cooler climates.
So far the system is flawless, the fridge can run infinitely without ever being connected to the car OR if there is little sun, just driving around a bit allows the aux battery to be topped off without any additional load on the engine.
