Couch I'd put up on the vehicle (5)
I believe the answer is:
divan
'couch' is the definition.
(I know that divan is a type of couch)
'i'd put up on the vehicle' is the wordplay.
'put up' is a reversal indicator.
'on' is a charade indicator (letters next to each other).
'the vehicle' becomes 'van' (van is a kind of vehicle).
'id' backwards is 'di'.
'di'+'van'='DIVAN'
(Other definitions for divan that I've seen before include "Sideless, backless couch" , "Backless seat; bed" , "Viand (anag.)" , "Piece of furniture" , "Couch - bed" .)
