from brands to dover then dunkurqe to the camp site is aprox 325 miles if you follow e42 all the way to german border and geting of at prum
so if your car does 35 to the gallon will aprox 10 gallons
if your car does 10 miles to the galoon will be 325 diveded by 10
only you know what you car does to gallon or what your range is on a tank of fuel remembering for most of that journey are on the motoreway so more miles to the gallon than normal town driving
hope this helps
