Car Fridges , help with some stupid questions please

[Winnie]

So ....i need a new esky, the one i like is about $300, but now im half thinking i should put that money toward a 12V fridge ?

I've got the Gold Engel, it's awesome. If you do somehow spill crap in it you can just soak it up with a towel and give it a wipe down inside.
Travel bag is good but not necessary. I would spend the extra money for one though. Keeps the fridge cooler and protects from scratches etc.
In the cooler months I have run mine for a week without using the car at all and it still started. Warmer months it will last two days. But this is not good for the battery, you really SHOULD use dual batteries but I went with the single battery for 12 months.
Don't know about other brands but the Engel has a thermal cut out. Keep things away from the vents but there are vents on both sides and the back so partial blockage would be okay I would think.
The slides are just convenience. But say if your fridge is on top of a set of drawers the lid might hit the roof before you can get into it so would be necessary there.
I use cans because there is no chance of them breaking inside the fridge and I can crush them to take up less room when taking them home. But I have used bottles no dramas, just more rubbish to take with you.
Fridge is definitely the way to go!
