Truck landed carrying silver (5)
I believe the answer is:
wagon
'truck' is the definition.
(thesaurus)
'landed carrying silver' is the wordplay.
'landed' becomes 'won' (both can mean to secure something eg a job).
'carrying' indicates putting letters inside.
'silver' becomes 'ag' ('Ag' can be a synonym of 'silver').
'won' placed around 'ag' is 'WAGON'.
(Other definitions for wagon that I've seen before include "Cart; rail truck" , "Vehicle for transporting goods" , "Four-wheeled goods vehicle" , "Wild West trail vehicle?" , "Vehicle carrying goods" .)
