Portable freezer recommendation for Fish

[Macdrizzle]

Hi,

The family and I are planning on doing a BC trip this spring for some chinook salmon. Will be planning on taking the trailer. I was just wondering what are some recommended setups people use to preserve their catch when you're out and about in nature.

Would like to avoid renting a place or AirBnB so looking at outdoor camping type scenario with freezers. I know many of you are quite handy and creative with these things and looking for some ideas and setups.

Thanks!

Mike
