Two-zone fridge extension

[threedogs]

Hi this may have been done before so feel free to redirect me.
I'm thinking of purchasing an extension for my 40 litre Engel, TWO ZONE.
does anyone have one and are they worth the $$$$$. 60 ltres is just too
big for my needs. Which is food for 6 for a weekend normally. Beer duties are
left to my Baileys Icebox. [Best icebox ever] imo.
Any thoughts good or bad.

You want to turn your 40l into 60l which is going to be to big? is that right.

My mate has one and its great as he can change to 60 when he need to depending on how much stuff he needs. Works well I think. Bit pricy tho

There a couple on gumtree for sale ATM around 200-250 bucks
