DH and I have just bought a Coleman Xtreme coolbox for trips (all of them really) where we have no EHU and our electric coolbox is currently just acting as a fancy storage box.
It claims to keep ice cold for 5 days which sounds brilliant. If you have one, have you found this to be true and what have you found the best way of keeping everything else cold - ice packs/ice in a bag/tight packing/loose packing etc.?
Also will one ice pack last a weekend or will we have to use the campsite freezer every day or so, assuming there is one?
Brilliant, thanks Piffpaffpoff. Great ideas, particularly freezing bottles of water. We have a load in now so I will get those in the freezer ASAP for the weekend. We are going away to a festival so freezing ice packs wobn't realy be an option, so I will just put in as many frozen meals/drinks etc as I can.
