Why are the Wheelbases of Alaskan Trucks so long?

Someone asked a question on Facebook about why the wheelbases of big rigs in Alaska are so long.  Jack says they are so long in order to fit extra long loads.

Here is a photo of the long wheelbase being utilized:

Down in the states, the wheelbase would be much shorter on most trucks.  In other words, the wheels would be much closer to the body of the truck and this sized pipe would result in more rear overhang, thus needing more permits and a more complicated set up.  So to avoid that, the wheelbase has been lengthened, since these kinds of loads are commonplace in Alaska.

Since Jack has a long wheel base he can haul another trailer behind this one, as seen here:

This is the second trailer – it has a load of sheet pile (sheets of metal that are driven into the ground and used for road construction or for bridge construction).

(In the first photo you can see part of the second trailer but it’s hard to make out because there is another trailer of pipe behind it.  In the second photo I erased the pipe behind so you can see the load on the second trailer better.)

Here are a few more photos of the Salcha-Valdez pipe haul.

The last piece of pipe being loaded!

Jack is so happy to be on his LAST VALDEZ RUN so he can get back on the Dalton!!
