Realy just a hey look at me Wank factor for 4wd IMO, But each to their own .. Two mini kegs roughly two cartons of beer and not easily as portable .
Considering you can use the DIY Breweries and can your own favourite drop and still be about 50 / 60 % the cost of store bought, recommended to be kept refridgerated, though I have spoken to quite a few that dont and have had no problems with spoilage .. they take minimum of 10 cartons away every Christmas holidays for the group and keep them in the shade till wanted to be chilled .
