Heuhen, I don't think I have ever seen a Scania oil field truck or even a Scania that can do light duty stuff off road
, and the Kenworth T800 actually has a very tight turning radius, with the front wheels able to turn to 51 degrees IIRC.
Scania Normally build mostly roads truck, long liner and things like that, But when there come to off-road vehicles, scanias do deliver they powerful V( engine to other Swedish company's, In fact the CV 90 have a Scania engine (not an V8, i think!), but if you want a truck that is small can move anything and can do it every where, on or off the road or in the mountains, then you need the classic and famous Mercedes Unimog!
This is one of the new one:

But if you need to move something silly big, and 200+- hp and 1500 Newtons isent enough, then this one, a 1000 hp V10 ****** Newton-truck can do it:

And if non of them work the you either need a Russian Sibir truck or an tanks!
