Ahem... your link and description got me confused, do you mean truck combo like this (without the timber load):
And clarifications:
Define "full rights"... and does it have to have any detail on the underside of the truck/flatbed - not that polybudget would really allow that even if wanted? And what maps (color/diffuse, specular etc) are needed and in what resolution? And what about rigging/setup... is it enough to have have separate tires that you move to right position and animate with code,or should it have boned wheels and tire rotation animation (extra work)?
Basically something like this would be quite fun to do for me, I have done trucks like these before (3DMark2001 for example). Time limit is bit tight though because '07 (year, not Mark!) is coming and all the related celebrations & hangovers...
