I have seen first hand what a trailer out of align will do, it will not track properly,
this isn't a design problem, it is the trucking companies problem and some companies
don't seem to be to fussed about fixing this. The regulations for these units should be
tougher even for be doubles. Maintenance is a big problem, I remember a couple years ago
when the police had a crack down on faulty trucks, one trailer had cracked right through
the main rails. there for it had very little strength. The companies should be forced to
have higher maintenance on these units.
