Nice job Tim,
I can think of a few customs that would benefit from such a low cab, the most challenging would be a car transporter and the easiest a small box van, the front of the box could come over the top of the cab, you know what I mean.
If your into your trucks you should come out with me oneday and change a few tyres on them, theres some strange looking vehicles around Grimsby and Immingham docks.
