Thanks. I see now. And BTW, what a cool set! I'd never seen that one
before.

Not really. Remember that in the largest truck they do, the cab floor is
20-30 feet off the ground. You could use Big Foot wheels with a full
blown articulated suspension with rack and pinion steering and a
differential and still have room to mount an engine model in all that
space (the truck would no doubt be a good 20 studs wide, and the cab
floor would be 8-12 bricks off the ground.)
> Besides, how would the dump be constructed? Any ideas?
Either something done with hinge bricks, or lots and lots of plates
sandwiched around a technic axle and beam skeleton. Again, the dump body
holds 3-400 TONS of material so it's HUGE. It's amazing to think that
they move around with no more engine power than an over the road truck
(3-400 horsepower, about 2-3 times that of a normal passenger car
nowadays). It's all in the gearing.
These trucks are so large that they are shipped in pieces and assembled
on the site. They take up 3 lanes of roadway so never dare venture out
onto highways.
