A fairly stupid question I know but I’m unsure so I’m asking lol
A set run mate.
i.e. a wagon in my place trunks up north every afternoon to collect and bring back goods for the following day
Trunking is what I would like to do one day. 
Trunking is city to city motorway work.
Boring as hell. You join the motorway, sit at 56 for hours and come off again.
i do production trunking at least 2-3 days a week from production plant, to a DC, its varies between 4 production plants so its not as boring as it could be
Jimboy is trunking between Garanor and Luton
