My two cents is don't take frozen stuff.
I don't remote travel/camp much these days but IMHO the best bet is cryovac and refridgerate (no need to freeze cryovac meat etc).
We also used to take a selection of the precooked meals like these https://www.snowys.com.au/camping-food
The advantage of them is that if doing longer travel legs at afternoon smoko we would boil extra water, put the hot water in a thermal cooker with the meals and when we pulled up Dinner was piping hot ready to eat so we could chillax.
If we were camped or stopping early then we would do a cryovac cookup.
