Are you able to share a link of your fridge you are recommending/have experience with. CheersTBH cool boxes just don't hack it in really hot conditions IMO. They struggle above 25C and in desert conditions are useless. They also consume a lot more battery juice than compressor fridges so, if you're static for a few days, you run the risk of running the battery flat. I bought an Engle some 15 years ago; it's expensive but still going strong and superb.
