You can tell that caravans are cool again by the spate of books on the subject, including this Caravan Cookbook by Monica Rivron.
The Rivron family (Monica is wife of comedian Roland Rivron) have been caravanning for over 10 years, which has given them plenty of experience of preparing meals in a limited kitchen space. The book contains recipes for simple, but tasty meals, as well as guidance on what essentials to bring along from home.
The book is available from Amazon, priced £8.46.
