That is a very nice diagram gives a clear idea of what you have in mind. You might want to do the same type of diagram for a
solar charge controller in trailer with a deep cylce
battery,
solar panel on a portable stand to be positioned in sun and plugged into charge controller. I think you will see a marked increase in simplicity in that configuration.
I would consider a 12v /110v ac compressor type two way
fridge. When you are plugged in 0 battery drain, on battery...
100 watt panel is going to be approx 5.7 amp an hour charge. So you can figure plus 30 amp hr a day from
solar. Even a single 130 ah battery gives you 65 ah "in the bank" without going below 50% charge.
If you use 40 amp hour a day you have six days before you need to plug in.
You could also look to putting the chest
fridge you mentioned in OP on a slide out tray where the old ice box or
fridge was. Still keeps
electrical set up simple and contained in trailer. Slide out chest to get food, slide in when done. And I it might be nicer to have that food in trailer rather than in car.
More efficient energy wise too, insulated, shaded trailer vs car with all it's
windows. I know my car is a lot hotter than my trailer and any fridge is a heat exchanger, hotter ambient temp more it will run.
