Two appliances from Bridgwater were mobilised to a report of a vehicle on fire at Perry Green, Wembdon, Bridgwater at 01:19 this morning (Wednesday).
When the crews arrived they found a fire involving a people carrier and the exterior of a caravan.
Two breathing apparatus wearers extinguished the fire with a hose reel jet. The vehicle was completely destroyed by fire and twenty per cent of the caravan was damaged by heat.
The cause of the fire is believed to be deliberate. The Avon and Somerset Constabulary are investigating.
