[VAC] Re: Airstream Prototype

My farm wagons, (all five of them) steer like a car. Not like a red
flyer or horse drawn wagon. One of the oldest is made of car axles from
late 30's vintage Fords.

I don't find zero tongue weight to be beneficial. To prevent wander, the
hitch ball has to fit perfectly. With tongue weight the ball does fine.
Farm wagons with hitch pins and worn steering linkage have a strong
tendency to wander, more as speed and load increases. Further, lack of
tongue weight takes away weight needed at the tow vehicle drive wheels
for getting started and stopped.
