i’m an ex gregorys & interoute farm collection & liner driver & cant add much more than StokeTrucker or C-Kay other than take yer time & get used to the surges & slop
you don’t see many about now but also beware of twin potters, these trailers have two compartments in them , so you could get two surges / slops working against each other , now that really is a strange load to pull , also beware with these that if a twin has been filled without a unit hitched to it , the rear compartment maybe fuller than the front , & this makes the backend of the unit very skittish & light , real nasty on roundabouts !
slow on corners & be wary of part loads as again on uphill gradients can take the weight off the rear end .
have seen part loaded tankers try to stop at traffic lights only for the slop to push them out into oncoming traffic
if you have to collect a trailer from a reload site , the farm collection drivers will fill the reload sheets out but you will need to work out your gross weight
most trailers have a sticker giving it’s tare weight & another for the tank capacity, all you need to know is the approx weight of the unit
from the loaded litres you can work out the GVW
TOTAL LITRES x 1.0237 + TRAILER WEIGHT + UNIT WEIGHT = GROSS WEIGHT
ask in the office for a sheet of trailer numbers & corressponding weights then write in that equasion & you can work out what you want whereever you are with any tank
