Carbon monoxide alarms are now fitted as standard to most new vans, as manufacturers become increasingly aware of the hazards this poisonous gas can cause.
It is produced from fuel-powered equipment such as barbecues, but has no colour, taste or smell, making it very difficult to detect.
To ensure your next holiday is free from this risk, Spruce Safety Products are offering 75 readers the chance to win one of its hi-tech FireAngel CO-9X carbon monoxide alarms, worth £20 each.
The alarm has a seven year life, without any need to replace the batteries. It is also compact so ideal for fitting in the van.
For your chance to win one of these alarms enter here before midnight on 18 July.
