Ran off with sparkling wine, perhaps towing it away (7)
I believe the answer is:
caravan
'it away' is the definition.
The definition suggests a singular noun which matches the answer.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for caravan that I've seen before include "Group of desert travellers" , "Camel train" , "Mobile home" , "Desert convoy" , "Group of desert voyagers" .)
