I think you and I are looking to request the same trucks from someone willing to flex in some 3D modeled bones on wheels. I've suggested donations as a reasonable compensation for the labor involved with the level of Harry Potter magic that I still don't understand involved.

I would be supportive of square body trucks, and would stream builds of whatever comes along.
Certainly the Specialty packages for Camper, or Explorer trims for the 67-79 F-series. Maybe the Scottsdale, Prospector Bow ties. Throw in some D100, 150s and ramchargers, and you almost have all the popular makes to what made Monster Jam legendary. (Mods, add lifted variations please)

I'll see who else I can wrangle on this thread, and see if we can make it a yarn's worth.
