I used to haul sap with an old stainless milk tank 1500 gal mounted on a chevy c-60. It was a great rig because it was setup so a majority of the weight was carried on the rear axle. Truck would go threw mud and snow like crazy especially with a set of chains on. However, on our winding roads, you had to pay attention like crazy going into corners especially with less the absolute full load because the slosh of sap would want to put you over the bank. Hauling liquid is like no other payload. It has a mind of its own and doesn't like to change direction of movement.
