Things to take on board or move into road transport (6)

I believe the answer is:

cargos

'things to take on board' is the definition.
(cargo to be transported)

'move into road transport' is the wordplay.
'move' becomes 'go' (to go is to move).
'into' is an insertion indicator.
'road transport' becomes 'cars' (road vehicles).
'go' inserted inside 'cars' is 'CARGOS'.

'or' is the link.

I've seen this clue in The Guardian.
