My parents had a fibreglass pop top "caravan" as they were called back then (and in my mind still are), with a lovely blue racing stripe around it ... brand unknown (just can't remember). It was a good old beast. Blue canvas pull out beds, 12V "bar" fridge, 4 burner gas stove and seating for 4 at the dining table. We spent many holidays enjoying the fresh air and Getting Out There.
One thing dad HATED about it, was the fact that the "cogs" were plastic and often needed replacement as they rounded off or broke completely. He often was fixing it instead of enjoying the camp like we kids did. He reckoned that if they made the pulley system properly, then it would have been The Perfect Thing.
