Solar power requirement to add a portable Fridge/freezer to my rig

Im thinking of adding a 20l fridge/freezer to supplement my inbuilt 12v/240v compressor fridge in my Sprinter RV.
My power source is mainly solar - 2 x 80 fixed panels on my roof and a 120 portable blanket - or 240v when available. I have one house battery. Im thinking this wouldnt be adequate to run an additional fridge/freezer.
How can I adapt my current power system to accomodate this please?
I would value the thoughts of other GNs
(Discussions with fellow travellers have given me much food for thought. Engel comes highly recommended but Im told it runs constantly and that a WAECO runs intermittently thus using less power. Your thoughts on this would be helpful too please.)

Hi
battery size 120ah absolute minimum preferably 2 x 120ah
solar 200watts per 100/120ah battery
dc 2 dc charger so batteries are always fully charged when u arrive at site Projecta 25amp or more $$ Enerdrive 30/40 amp
I thought Engel was more efficient due to the compressor type it used .Yes mine has a thermostat .
40--60ltr fridge ?
The above is a typical van setup
Yes there are thermal electric fridges than run constantly . These consumes a lot of power . Typically 15--30ltrs . Not recommended
