Aspiring author seeks help

While I'm away in my caravan I like to take advantage of my surroundings and scribble away in an exercise book creating stories.

I am thinking about beggining a story (full length novel - who knows?) about a pair of crime solving friends who just happen to tour the UK in their caravan.

I am thinking of setting these adventures in the 1950s or 60s (haven't decided yet) and I was wondering if there is anyone out there who remembers what caravan holidays were like back then?

I would be extremely grateful if anyone would share their memories with me so that I can get a feel for the times.
