Topless Russian camper (3)
I believe the answer is:
van
'camper' is the definition.
(van is a kind of camper)
'topless russian' is the wordplay.
'topless' means to remove the first letter.
'russian' becomes 'ivan' (I've seen this before).
'ivan' with its first letter taken off is 'VAN'.
(Other definitions for van that I've seen before include "Transporting vehicle" , "Light lorry" , "Trade vehicle" , "Commercial vehicle at head of army" , "Covered wagon" .)
