So I am in the market this year for a fridge freezer, it seems to be my best option to go with an ARB because of the quality and the price.
I have talked to someone who owns a 50 and has recommended me to go with a 63. I am wanting to hear what you have to say.
The ARB fridge uses a quality Danfoss compressor like at least 6-7 other brands do.Even Engels are making some of their fridges with a Danfoss comp after using the sarafuji swing compressor for 40 years.
So I dont see brand as the most important thing,its more about the features.
The main points to consider on fridges
1 Power efficiency,the amount of thermal insulation makes a big difference but takes up room.
2 Decent grab handles.They are a pain when they are full and you have to carry them yourself with crap handles.
3 Which way the door opens.Some are fixed,some can be reversed.
4 Internal shape. Deep narrow fridges are great for long term storage,but for daily use,wide shallow firdges are better because you dont have to keep turning things over to get to items at the bottom.(after 4-5 days on the road you will understand perfectly

)
But they do take up more floor space then deep fridges.
5 Mains power.can you plug it directly into the mains power or do you have to buy a 12v/24vpower supply?
6 Parts availabilty and warranty.Lots of cheap fridges hitting the shops these days,many of them are coming from the same factory in China which sells them for $85 and end up costing $600-$700 in the west.
As to size of the fridge.Bigger is better on fridge size and shape comes a close 2nd
My 50 litre Waeco is now a beer fridge under the computer desk,the 80 litre Waeco goes with me everywhere.
It only uses slightly more power ,but as I mentioned before,BIG wide and shallow wins me over every time.
A lot of owners want to use their car fridge as a freezer.
IMO,you are better off taking chilled food rather than frozen.Ive got one of those vacuum machines that sucks the air out and seals it in a bag.Great investment!
You can restock your fridge every 2-3 days or even daily if you want.
Soft chilled food is easier to pack than rock hard frozen.
Keeping things frozen on the road uses twice as much power as keeping food around 1-2c
