I believe the answer is:

mobile homes

I'm a little stuck... Click here to teach me more about this clue!

'trailers' is the definition.
('mobile home' can be a synonym of 'trailer')

'drove truck back around another hole' is the wordplay.
I cannot quite see how this works, but
'around' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
'another' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
'hole' could be 'o' and 'o' is present in the answer.
This explanation may well be incorrect...
