We've had one for a couple of years and has served us very well. Use in our Trigano Olympe. Normally use it on 240v but have used it on gas and it is very good even when it's 30 degrees outside. Plenty of room for the essentials and my beer and even makes ice cubes as well.
The biggest bonus for us over our old electric coolbox is that it's silent so it doesn't keep us awake at night!
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
