After weeks of not hearing from designer G. Rutka, I thought I'd post this reply from DAF trucks:

Dear Lorenzo,
That is a great idea. Of course you are free to do so!
Do you mind to share with us the results?
Best,

Of course I emailed him my recolor of the Campbell DAF XF and I plan to do at least 1 more. My understanding is DAF doesn't just allow recolors, they encourage it, and only ask that we show what we've done. This permission is specifically for the paper models at this website:
Paper models - DAF Trucks N.V.
I know at least 2 others do truck recolors, so this is good news. Send me a PM when you're ready to submit to DAF and I'll send you Mr. Kerstiens' email.
