Nothing says 'I'm a dork' like a cab-over truck.

At least that's the reputation they've got in our shop. Most of the truck you'll see on the tight roads in Europe are gonna be cab-overs. We've got more room over here, so large-cars and condo cabs are they way to go.
Speaking of long trailers, I read a few weeks ago some bloke in Australia pulled over 3,000,000lbs on a hundred-something trailers with a stock Pete for 100m.
Keep in mind most of the big trucks you see on the road can be pulling 100x more weight than they actually do because we have to turn our trucks down to meet US emission regulations.

These new fuel laws are gonna kill us.
