Talked about cheap American trailer (8)
I believe the answer is:
'american trailer' is the definition.
(US term for someone who trails along)
'talked about cheap' is the wordplay.
'talked' becomes 'spoke' ('speak' can be a synonym of 'talk').
'about' indicates putting letters inside.
'cheap' becomes 'low'.
'spoke' enclosing 'low' is 'SLOWPOKE'.
(Other definitions for slowpoke that I've seen before include "Dawdler" , "Laggard (in America)" .)
