Cool and unusual trucks found on Big Lorry Blog

An older semi in Brazil, and I like the grill, full length and looking like a 1940's car design Cool. Looks like the back wheels also steer Looks like water cannons on top, and armor covering the back This and the last photo in this gallery are both 4 wheels under the cab. It seems similar to an F.A.R. http://justacarguy.blogspot.com/2009/01/three-wheeled-tractor-trailer-rig.html but definitly

I didn't expect to find a drag racing semi at SEMA
