Hi Reg, My husband and I also run tippers and we have one person we contract to so I understand your plight. Is there any way that you can contract direct to the primary source instead of sub contractor to the contractor? It would be better rates. Another thing that has helped our cash flow is a fuel card although you have to be diligent in paying for it. We have found that the rates we are on the good side to stay with this one contractor then with many others we have found so don't be afraid to look around. I hope that helps a little and hope you can sell up and retire comfortably.
