Burglars climbed a security fence at a Somercotes storage facility on Cotes Park Lane, before taking a caravan from the compound.
Two men first entered the site at 5.20pm on Sunday, January 19.
A CCTV camera captured the men opening a gate, while a third man drove in with a 4x4 vehicle.
The off-roader had oversized wheels, spotlights and bull bars.
A wheel clamp was removed from the caravan and it was driven away.
If you have any information which could help police, call the force on 101.
