Dodgy American parking in camp (7)
I believe the answer is:
suspect
'dodgy' is the definition.
(I've seen this before)
'american parking in camp' is the wordplay.
'american' becomes 'us'.
'parking' becomes 'p'.
'in' indicates putting letters inside.
'camp' becomes 'sect' (sect is a kind of camp).
'us'+'p'='usp'
'usp' going inside 'sect' is 'SUSPECT'.
(Other definitions for suspect that I've seen before include "Possible criminal - doubtful" , "Have qualms about" , "Fancy" , "Imagine to be true" , "Believe (something) possible or probable" .)
