the F450 King Cab they have

When I was in the US recently I figured out that Ford F150s were ludicrously big, F250s even bigger, and "crew cab" F350s (there was one in Sonic Blue's car park) utterly ludicrously big. I didn't even realise it went up to 450, but a look at Ford's web site shows the top of the range is the 750...
