We have a camping trip to the West of Ireland planned in the Summer and as we have an ancient VW camper, we are splitting the journey with an overnight at the port and will therefore need to keep things cool for longer than usual before even arriving on site.
We currently have two standard sized coolboxes, one of the cheap ones you can pick up in any supermarket and a more expensive one that can run off the cigarette lighter in the car, or an electric hook up.
I was watching a youtube video about the Coleman boxes the other day and found out that the reason the cheap boxes are a bit hopeless, is that they aren't actually insulated, they just have air between the wall and lining, whereas the better brands are fully insulated to keep the inside cool for longer. Sure enough, I went and knocked the side of ours and its not insulated at all.
So, it seems we are going to need a decent, well insulated box for our trip, preferably larger than the standard picnic sized boxes, but not huge as we are going to be overloaded as it is. Oh - and we are broke at the moment, so need something cheapish, but effective.
Any recommendations?
