On Sunday, between 9 pm and 10.30 pm, a grey Compass Casita 840 caravan was stolen from Hardhills Smithy, Castle Douglas.
It was last seen passing through Dalbeattie, being towed by a black 4×4.
And the following day, a white Elddis Supreme 554 2017 model caravan was taken from South Bowerhouses Cottage, Ruthwell, Dumfries, between 9 pm and 10.45 pm.
A spokesman for Police Scotland said: “We urge caravan owners to review any security measures they have in place and to take steps to reduce the chances of becoming a victim.”
They have also advised people to research different types of alarm and tracking systems, use robust wheel clamps and ensure vehicle registration numbers are etched onto all glass surfaces and vehicles identification numbers (VIN) are registered on a recognised database.
Police are appealing for anyone who has seen the caravans or who saw anyone or any vehicles acting suspiciously in the area, to contact Police Scotland on 101 quoting PS-20210906-3715 for Ruthwell, or 0502 of 06 September 2021 for the Castle Douglas theft.
