Lifting requirement for tanker drivers (for future refrence)

If you pump it off why cant your back suck it back into the trailer? Might be less hassle than dealing with heavy hoses.

Nightwind, I would try to corner a couple of drivers and see what they say. Like some have posted the hay baler girl might have inflated the numbers. You might have to lift a hose some to get some product out of it in some unusual circumstances but if you are pumping off or back sucking a common practice is to coil the hose (loop) if there is enough and roll it out that way.
