Yes it is very heavy, especially when you properly configure it
with 10 wheels.  Has anyone tried to make a complete 18 wheeler
based on the 5571?

I've got enough tires, but that would be one big box for
the trailer.

That sounds like quite a challenge.  The 5571 model is pretty heavy.
I wonder if the most recent black Technic Super Car has been
motorized.  I suppose so, but I haven't followed much Technic Talk.
Are the two models of similar mass?

Unfortunately, I don't have the super car, so I couldn't tell you whick
weighs more.  The 5571 is *heavy* and that's why my motorization didn't
work.  I tried to use two geared motors and extra gears for the rear
wheels and an old motor for steering.  It's too bad it didn't work - the
motors fit perfectly.  The two new motors fitted under the bunk in the
sleeper portion and the steering motor fitted in the same space as the
original steering.  I was able to place a touch sensor behind the front
bumper which was spring loaded.  I even tried to put real lights in the
headlights, but the fender got in the way of the bulky LEGO wiring.
The motors worked (slowly) at about half the finished mass.  However,
when the whole thing was finished, it stalled.  I was sick of gearing it,
so I quit.
If someone wants to try to do this, please let us know how it goes.  As I
said, there's plenty of room for the motors, the gearing is the problem

Sounds very nice, and realistic, too boot.

Thanks!
