The hapless thief took his chance to make off with the caravan parked at Billingsluttningen in Skövde by connecting it to the back of his car, according to Sveriges Radio Skaraborg.
But little did he know that he was also taking the caravan's owner along for an impromptu nightime drive.
The thief discovered his unwelcome booty only after making his getaway, when he pulled over and attempted to force entry into the mobile home.
The caravan's owner, who had been abruptly woken from his slumber when his holiday abode had been fastened to the thief's car, then screamed at the would-be intruder.
The resultant shock was enough to persuade the thief to flee the scene, empty-handed.
Skövde police have been supplied with a full report of the incident and have classified the crime as attempted theft and endangerment.
