good luck glen
i used to load out of hatfield as a return load when i worked at wincantons they always seemed ok when i was loading out of their.
but wincantons used to get some stick if drivers did not turn up on time to pick up there load we used to pick up loads for weymouth and south and our night shift used to deliver it tipping was always ok.
hope it works out for you but time wil tell only you can decide
good luck
