Andy, I've always been impressed by your work in the past, so I'm excited to see what comes out of this. All this talk of big trucks got me wondering what size of trucks are we allowed to run here in Alberta, Canada...
Regular (single trailer) semis can be 23m (75') long (total length), with a maximum 16.2m (53') trailer.
A-trains / B-trains / C-trains (semis with two trailers) can be 26m (85') long without a special permit.

Yup, it's true.
Rocky Mountain Doubles are a 53' trailer and a 28' trailer. In Alberta, they can be up to 31m (102') long.
Turnpike Doubles are double 53' trailers. In Alberta, they can be up to 38m (125') long.
Triple Trailers are three 28' trailers. In Alberta, they can be up to 38m (125') long.
These last three require a special permit, but that doesn't seem to be too hard to get. As well, they're limited to the more major roads in the province.

Turns out we've been doing this in Alberta for a while. Logging trucks can be 30.5m (100 ft) long, with a rear overhang of logs of 9m (30 ft). That overhang can cause problems at intersections, swinging into the lanes of oncoming traffic, so they put up warning signs in logging country.

The really crazy stuff is the trucks they send on the high and wide load corridors. These highways are designed to allow vehicles up to 9m (30') wide and 9m tall to pass. That makes for some monster loads, mostly of industrial components headed to the Oil Sands in Fort McMurray (imagine shipping oil refineries by truck...). Any chance you want to add some of these megaloads to your collection Andy?
