Id just like to share my first attempt at kit-bashing with you. Im not at all certain that you can mount a crane on a tracter unit (now I think of it - Ive only seen them on rigid chassis). If anyone out there knows otherwise, Id be glad to hear from you. 
No matter what, that’s a good looking combo and a nice build. I have the same idea for a build I’m doing for my cousin. The build it self has stalled but now that I’ve seen yours I just might take it up again.
Cheers!

Looks good regardless, great job.

Very nice build. I have no idea as to accuracy, but it looks real good.

I am a professional truck driver and although I don’t recall seeing quite that combination, I don’t see any reason it couldn’t be done. Looks great.
