Firefighters spent more than three hours tackling a blaze in Haddenham on Sunday night.
Crews from Sutton and Cottenham were called to Hill Row Causeway shortly after 10pm to reports of a caravan on fire.
They arrived to find three large storage containers, a car and a trailer were also alight. The fire was under control by about 1.45am.
The cause of the fire is believed to be deliberate. Anyone with information should contact the police on 101 or the independent charity Crimestoppers anonymously on 0800 555111.
