Could the truck actually weigh more?  Just a thought.  Could the problem be
similar to the fan cart problem?  If a cart with little friction in the wheels
is propelled by a fan, it will move opposite the direction of air flow.
However, if a sail is attached to the fan cart such that it is perpendicular to
 the air flow, then the cart will reverse directions.  The explanation is
based on the conservation of momentum.  Just sumthin' to think about.
                                      gotta go for now,
                                                       dt
