I know turning radius can be affected by tandems and tag axles and contemporary coaches have countersteering tag axles to prevent the 'subordinate' axle from scrubbing it's tires in the sideways motion of parking lot and corner turns. In trucking when you have three and four or more axles on a trailer you also have lift control or else you can't turn the trailer without dragging some of the tires sideways, causing wear and tear on the tires and burdening your engine trying to overcome the lateral drag. I know the problem isn't as pronounced in a tag axle or tandem coach configuration but I figured it's still a minor factor.
I appreciate the feedback and insight.
I ran about 250k miles in my Model 10 (aft tag) and the only time it was "bouncy" was at a certain speed if I hit a big bump it would initiate kind of a poirpising motion. I would slow or speed up just a bit and it would stop.
I rode in a couple of Model 1's & 5's (forward tag) and I don't think that they were quite as smooth as the later coaches. What was the difference: tag placement or 30 additional years of suspension wear???
