Thanks Gents.
This is all a learning curve for me. My mate has a an Aeropress unit. Looks nifty and a little backpacker style butane gas bottle and burner which packs away light which doesnt do a bad brew.
I also have a ROK lever press machine which I could also use. Crema is harder to create with that, but it works similarly to a manual machine in that it plunges the brew at reasonable pressure but manually.
I also cook with the camp fire and can boil water with a cheap stove top kettle I bought.
I guess if I settle for that style of coffee while Im out bush, then all I need is power to run the fridge for a number of days and charge devices and such.
Here is a unit I dont mind the look of

Also, I want to be able to charge the battery when the car is running/moving via an anderson plug if that is viable. I can buy a 200w solar panel setup from 4wd SC fairly cheap too for added convenience.
The reason I want to go the Lithium battery is reducing weight. My upper body strength is not good and lifting a regular AGM battery in an out is not as easy as it once was.
Just contemplating whether this unit

Ultimately, less attaching units is a good thing due to space and weight.
