Heres another one of his - 6x4 trailer
"If need pay take it away 6x4 clean as u see tow cupling is big one can fit over 50 m but loose can close the gab by rapping tape and cardboard and then tie it down or can sell u a tow ball $35 extra need call"
So I think that translates to " if the coupling is too big for your towball, just wrap it in duct tape and tie it down
And don't go over too many bumps...
