Flat Towing and keeping the wheels straight

Does anybody really know why some vehicles will follow and why some won't.
The answer is caster. Most if not almost all vehicle with manual steering
will have their caster set near zero. Positive caster helps the wheels
return to center and keeps them going straight at speed. The down side to
positive caster is it adds increased resistance in steering. Most vehicles
with power steering track better just because of this. Case in point, I had
a 78 Jeep CJ5 with manual steering. It was the most difficult little SOB to
flat tow. I added tapered shims to add posotive caster and it changed the
whole complexion of the Jeep. A while back I moved an M35 for a fellow and
this thing wouldn't track for nothing. As a quick last chance try, I removed
the tires from the 3rd axle and and let the back squat about 8" off the
ground. I accomplished this using chains tying the 3rd axle to the frame.
It made a very noticeable difference and I was able to get it moved. Just my
findings and food for thought!
